    ftrace: do not trace library functions
    
    make function tracing more robust: do not trace library functions.
    
    We've already got a sizable list of exceptions:
    
     ifdef CONFIG_FTRACE
     # Do not profile string.o, since it may be used in early boot or vdso
     CFLAGS_REMOVE_string.o = -pg
     # Also do not profile any debug utilities
     CFLAGS_REMOVE_spinlock_debug.o = -pg
     CFLAGS_REMOVE_list_debug.o = -pg
     CFLAGS_REMOVE_debugobjects.o = -pg
     CFLAGS_REMOVE_find_next_bit.o = -pg
     CFLAGS_REMOVE_cpumask.o = -pg
     CFLAGS_REMOVE_bitmap.o = -pg
     endif
    
    ... and the pattern has been that random library functionality showed
    up in ftrace's critical path (outside of its recursion check), causing
    hard to debug lockups.
    
    So be a bit defensive about it and exclude all lib/*.o functions by
    default. It's not that they are overly interesting for tracing purposes
    anyway. Specific ones can still be traced, in an opt-in manner.

    ftrace: fix lockup with MAXSMP

      calling  anon_inode_init+0x0/0x130

    Compiling a kernel with allmodconfig or allyesconfig results in tons

    Increase this to 2048, so these warnings don't distract from the real

    |     Merge branch 'auto-ftrace-next' into tracing/for-linus
    
    turns out that i made this mistake in the merge:
    
      ifdef CONFIG_FTRACE
      # Do not profile debug utilities
      CFLAGS_REMOVE_tsc_64.o = -pg
      CFLAGS_REMOVE_tsc_32.o = -pg
    
    those two files got unified meanwhile - so the dont-profile annotation
    got lost. The proper rule is:
    
      CFLAGS_REMOVE_tsc.o = -pg

    fix dangling zombie when new parent ignores children
    
    This fixes an arcane bug that we think was a regression introduced
    by commit b2b2cbc4b2a2f389442549399a993a8306420baf.  When a parent
    ignores SIGCHLD (or uses SA_NOCLDWAIT), its children would self-reap
    but they don't if it's using ptrace on them.  When the parent thread
    later exits and ceases to ptrace a child but leaves other live
    threads in the parent's thread group, any zombie children are left
    dangling.  The fix makes them self-reap then, as they would have
    done earlier if ptrace had not been in use.

    do_wait: return security_task_wait() error code in place of -ECHILD
    
    This reverts the effect of commit f2cc3eb133baa2e9dc8efd40f417106b2ee520f3
    "do_wait: fix security checks".  That change reverted the effect of commit
    73243284463a761e04d69d22c7516b2be7de096c.  The rationale for the original
    commit still stands.  The inconsistent treatment of children hidden by
    ptrace was an unintended omission in the original change and in no way
    invalidates its purpose.
    
    This makes do_wait return the error returned by security_task_wait()
    (usually -EACCES) in place of -ECHILD when there are some children the
    caller would be able to wait for if not for the permission failure.  A
    permission error will give the user a clue to look for security policy
    problems, rather than for mysterious wait bugs.

    ptrace children revamp
    
    ptrace no longer fiddles with the children/sibling links, and the
    old ptrace_children list is gone.  Now ptrace, whether of one's own
    children or another's via PTRACE_ATTACH, just uses the new ptraced
    list instead.
    
    There should be no user-visible difference that matters.  The only
    change is the order in which do_wait() sees multiple stopped
    children and stopped ptrace attachees.  Since wait_task_stopped()
    was changed earlier so it no longer reorders the children list, we
    already know this won't cause any new problems.

    do_wait reorganization
    
    This breaks out the guts of do_wait into three subfunctions.
    The control flow is less nonobvious without so much goto.
    do_wait_thread and ptrace_do_wait contain the main work of the outer loop.
    wait_consider_task contains the main work of the inner loop.

    [PATCH] ocfs2: fix oops in mmap_truncate testing
    
    This patch fixes a mmap_truncate bug which was found by ocfs2 test suite.
    
    In an ocfs2 cluster more than 1 node, run program mmap_truncate, which races
    mmap writes and truncates from multiple processes. While the test is
    running, a stat from another node forces writeout, causing an oops in
    ocfs2_get_block() because it sees a buffer to write which isn't allocated.
    
    This patch fixed the bug by clear dirty and uptodate bits in buffer, leave
    the buffer unmapped and return.
    
    Fix is suggested by Mark Fasheh, and I code up the patch.

    Fix FADT parsing
    
    The (1.0 inherited) separate length fields in the FADT are byte granular.
    Further, PM1a/b may have distinct lengths and live in distinct address spaces.
     acpi_tb_convert_fadt() should account for all of these conditions.
    
    Apart from these changes I'm puzzled by the fact that, not just for
    acpi_gbl_xpm1{a,b}_enable, acpi_hw_low_level_{read,write}() get an explicit
    size passed rather than using the size found in the passed GAS.  What happens
    on a platform that defines PM1{a,b} wider than 16 bits?  Of course,
    acpi_hw_low_level_{read,write}() at present are entirely un-prepared to deal
    with sizes other than 8, 16, or 32, not to speak of a non-zero bit_offset or
    access_width...

    PNPACPI: add support for HP vendor-specific CCSR descriptors
    
    The HP CCSR descriptor describes MMIO address space that should appear
    as a MEM resource.  This patch adds support for parsing these descriptors
    in the _CRS data.
    
    The visible effect of this is that these MEM resources will appear
    in /sys/devices/pnp0/.../resources, which means that "lspnp -v" will
    report it, user applications can use this to locate device CSR space,
    and kernel drivers can use the normal PNP resource accessors to
    locate them.

    PNP: convert resource options to single linked list
    
    ISAPNP, PNPBIOS, and ACPI describe the "possible resource settings" of
    a device, i.e., the possibilities an OS bus driver has when it assigns
    I/O port, MMIO, and other resources to the device.
    
    PNP used to maintain this "possible resource setting" information in
    one independent option structure and a list of dependent option
    structures for each device.  Each of these option structures had lists
    of I/O, memory, IRQ, and DMA resources, for example:
    
      dev
        independent options
          ind-io0  -> ind-io1  ...
          ind-mem0 -> ind-mem1 ...
          ...
        dependent option set 0
          dep0-io0  -> dep0-io1  ...
          dep0-mem0 -> dep0-mem1 ...
          ...
        dependent option set 1
          dep1-io0  -> dep1-io1  ...
          dep1-mem0 -> dep1-mem1 ...
          ...
        ...
    
    This data structure was designed for ISAPNP, where the OS configures
    device resource settings by writing directly to configuration
    registers.  The OS can write the registers in arbitrary order much
    like it writes PCI BARs.
    
    However, for PNPBIOS and ACPI devices, the OS uses firmware interfaces
    that perform device configuration, and it is important to pass the
    desired settings to those interfaces in the correct order.  The OS
    learns the correct order by using firmware interfaces that return the
    "current resource settings" and "possible resource settings," but the
    option structures above doesn't store the ordering information.
    
    This patch replaces the independent and dependent lists with a single
    list of options.  For example, a device might have possible resource
    settings like this:
    
      dev
        options
          ind-io0 -> dep0-io0 -> dep1->io0 -> ind-io1 ...
    
    All the possible settings are in the same list, in the order they
    come from the firmware "possible resource settings" list.  Each entry
    is tagged with an independent/dependent flag.  Dependent entries also
    have a "set number" and an optional priority value.  All dependent
    entries must be assigned from the same set.  For example, the OS can
    use all the entries from dependent set 0, or all the entries from
    dependent set 1, but it cannot mix entries from set 0 with entries
    from set 1.
    
    Prior to this patch PNP didn't keep track of the order of this list,
    and it assigned all independent options first, then all dependent
    ones.  Using the example above, that resulted in a "desired
    configuration" list like this:
    
      ind->io0 -> ind->io1 -> depN-io0 ...
    
    instead of the list the firmware expects, which looks like this:
    
      ind->io0 -> depN-io0 -> ind-io1 ...

    ISAPNP: handle independent options following dependent ones
    
    The ISAPNP spec recommends that independent options precede
    dependent ones, but this is not actually required.  The current
    ISAPNP code incorrectly puts such trailing independent options
    at the end of the last dependent option list.
    
    This patch fixes that bug by resetting the current option list
    to the independent list when we see an "End Dependent Functions"
    tag.  PNPBIOS and PNPACPI handle this the same way.

    PNP: remove extra 0x100 bit from option priority
    
    When building resource options, ISAPNP and PNPBIOS set the priority
    to something like "0x100 | PNP_RES_PRIORITY_ACCEPTABLE", but we
    immediately mask off the 0x100 again in pnp_build_option(), so that

    PNP: support optional IRQ resources
    
    This patch adds an IORESOURCE_IRQ_OPTIONAL flag for use when
    assigning resources to a device.  If the flag is set and we are
    unable to assign an IRQ to the device, we can leave the IRQ
    disabled but allow the overall resource allocation to succeed.
    
    Some devices request an IRQ, but can run without an IRQ
    (possibly with degraded performance).  This flag lets us run
    the device without the IRQ instead of just leaving the
    device disabled.
    
    This is a reimplementation of this previous change by Rene
    Herman <rene.herman@gmail.com>:
        http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3b73a223661ed137c5d3d2635f954382e94f5a43
    
    I reimplemented this for two reasons:
        - to prepare for converting all resource options into a single linked
          list, as opposed to the per-resource-type lists we have now, and
        - to preserve the order and number of resource options.
    
    In PNPBIOS and ACPI, we configure a device by giving firmware a
    list of resource assignments.  It is important that this list
    has exactly the same number of resources, in the same order,
    as the "template" list we got from the firmware in the first
    place.
    
    The problem of a sound card MPU401 being left disabled for want of
    an IRQ was reported by Uwe Bugla <uwe.bugla@gmx.de>.

    PNPACPI: ignore _PRS interrupt numbers larger than PNP_IRQ_NR
    
    ACPI Extended Interrupt Descriptors can encode 32-bit interrupt
    numbers, so an interrupt number may exceed the size of the bitmap
    we use to track possible IRQ settings.
    
    To avoid corrupting memory, complain and ignore too-large interrupt
    numbers.
    
    There's similar code in pnpacpi_parse_irq_option(), but I didn't
    change that because the small IRQ descriptor can only encode
    IRQs 0-15, which do not exceed bitmap size.
    
    In the future, we could handle IRQ numbers greater than PNP_IRQ_NR
    by replacing the bitmap with a table or list.

    PNP: centralize resource option allocations
    
    This patch moves all the option allocations (pnp_mem, pnp_port, etc)
    into the pnp_register_{mem,port,irq,dma}_resource() functions.  This
    will make it easier to rework the option data structures.
    
    The non-trivial part of this patch is the IRQ handling.  The backends
    have to allocate a local pnp_irq_mask_t bitmap, populate it, and pass
    a pointer to pnp_register_irq_resource().

    This changes pnp_assign_dma() from a void function to one that

    it appears to never fail, just like before.

    PNP: dont sort by type in /sys/.../resources
    
    Rather than stepping through all IO resources, then stepping through
    all MMIO resources, etc., we can just iterate over the resource list
    once directly.
    
    This can change the order in /sys, e.g.,
    
        # cat /sys/devices/pnp0/00:07/resources     # OLD
        state = active
        io 0x3f8-0x3ff
        irq 4
    
        # cat /sys/devices/pnp0/00:07/resources     # NEW
        state = active
        irq 4
        io 0x3f8-0x3ff
    
    The old code artificially sorted resources by type; the new code
    just lists them in the order we read them from the ISAPNP hardware
    or the BIOS.

    PNPACPI: keep disabled resources when parsing current config
    
    When we parse a device's _CRS data (the current resource settings),
    we should keep track of everything we find, even if it's currently
    disabled or invalid.
    
    This is what we already do for ISAPNP and PNPBIOS, and it helps
    keep things matched up when we subsequently re-encode resources.
    For example, consider a device with (mem, irq0, irq1, io), where
    irq0 is disabled.  If we drop irq0 when parsing the _CRS, we will
    mistakenly put irq1 in the irq0 slot when we encode resources
    for an _SRS call.

    PNP: replace pnp_resource_table with dynamically allocated resources
    
    PNP used to have a fixed-size pnp_resource_table for tracking the
    resources used by a device.  This table often overflowed, so we've
    had to increase the table size, which wastes memory because most
    devices have very few resources.
    
    This patch replaces the table with a linked list of resources where
    the entries are allocated on demand.
    
    This removes messages like these:
    
        pnpacpi: exceeded the max number of IO resources
        00:01: too many I/O port resources
    
    References:

        http://lkml.org/lkml/2007/11/30/110
    
    This patch also changes the way PNP uses the IORESOURCE_UNSET,
    IORESOURCE_AUTO, and IORESOURCE_DISABLED flags.
    
    Prior to this patch, the pnp_resource_table entries used the flags
    like this:
    
        IORESOURCE_UNSET
    	This table entry is unused and available for use.  When this flag
    	is set, we shouldn't look at anything else in the resource structure.
    	This flag is set when a resource table entry is initialized.
    
        IORESOURCE_AUTO
    	This resource was assigned automatically by pnp_assign_{io,mem,etc}().
    
    	This flag is set when a resource table entry is initialized and
    	cleared whenever we discover a resource setting by reading an ISAPNP
    	config register, parsing a PNPBIOS resource data stream, parsing an
    	ACPI _CRS list, or interpreting a sysfs "set" command.
    
    	Resources marked IORESOURCE_AUTO are reinitialized and marked as
    	IORESOURCE_UNSET by pnp_clean_resource_table() in these cases:
    
    	    - before we attempt to assign resources automatically,
    	    - if we fail to assign resources automatically,
    	    - after disabling a device
    
        IORESOURCE_DISABLED
    	Set by pnp_assign_{io,mem,etc}() when automatic assignment fails.
    	Also set by PNPBIOS and PNPACPI for:
    
    	    - invalid IRQs or GSI registration failures
    	    - invalid DMA channels
    	    - I/O ports above 0x10000
    	    - mem ranges with negative length
    
    After this patch, there is no pnp_resource_table, and the resource list
    entries use the flags like this:
    
        IORESOURCE_UNSET
    	This flag is no longer used in PNP.  Instead of keeping
    	IORESOURCE_UNSET entries in the resource list, we remove
    	entries from the list and free them.
    
        IORESOURCE_AUTO
    	No change in meaning: it still means the resource was assigned
    	automatically by pnp_assign_{port,mem,etc}(), but these functions
    	now set the bit explicitly.
    
    	We still "clean" a device's resource list in the same places,
    	but rather than reinitializing IORESOURCE_AUTO entries, we
    	just remove them from the list.
    
    	Note that IORESOURCE_AUTO entries are always at the end of the
    	list, so removing them doesn't reorder other list entries.
    	This is because non-IORESOURCE_AUTO entries are added by the
    	ISAPNP, PNPBIOS, or PNPACPI "get resources" methods and by the
    	sysfs "set" command.  In each of these cases, we completely free
    	the resource list first.
    
        IORESOURCE_DISABLED
    	In addition to the cases where we used to set this flag, ISAPNP now
    	adds an IORESOURCE_DISABLED resource when it reads a configuration
    	register with a "disabled" value.

    PNP: make pnp_{port,mem,etc}_start(), et al work for invalid resources
    
    Some callers use pnp_port_start() and similar functions without
    making sure the resource is valid.  This patch makes us fall
    back to returning the initial values if the resource is not
    valid or not even present.
    
    This mostly preserves the previous behavior, where we would just
    return the initial values set by pnp_init_resource_table().  The
    original 2.6.25 code didn't range-check the "bar", so it would
    return garbage if the bar exceeded the table size.  This code
    returns sensible values instead.

    PNP: add pnp_resource_type_name() helper function
    
    This patch adds a "pnp_resource_type_name(struct resource *)" that
    returns the string resource type.  This will be used by the sysfs
    "show resources" function and the debug resource dump function.

    PNP: remove pnp_resource.index
    
    We used pnp_resource.index to keep track of which ISAPNP configuration
    register a resource should be written to.  We needed this only to
    handle the case where a register is disabled but a subsequent register
    in the same set is enabled.
    
    Rather than explicitly maintaining the pnp_resource.index, this patch
    adds a resource every time we read an ISAPNP configuration register
    and marks the resource as IORESOURCE_DISABLED when appropriate.  This
    makes the position in the pnp_resource_table always correspond to the
    config register index.

    ACPI: Disable MWAIT via DMI on broken Compal board
    
    If a system matches in this DMI table,
    Linux will disable MWAIT support for idle.
    ie. "idle=nomwait" is automatically invoked
    and C1_FFH and C2C3_FFH access mode are disabled.

    ACPI : Create "idle=nomwait" bootparam
    
    "idle=nomwait" disables the use of the MWAIT
    instruction from both C1 (C1_FFH) and deeper (C2C3_FFH)
    C-states.
    
    When MWAIT is unavailable, the BIOS and OS generally
    negotiate to use the HALT instruction for C1,
    and use IO accesses for deeper C-states.
    
    This option is useful for power and performance
    comparisons, and also to work around BIOS bugs
    where broken MWAIT support is advertised.

    ACPI: Create "idle=halt" bootparam
    
    "idle=halt" limits the idle loop to using
    the halt instruction.  No MWAIT, no IO accesses,
    no C-states deeper than C1.
    
    If something is broken in the idle code,
    "idle=halt" is a less severe workaround
    than "idle=poll" which disables all power savings.

    However, we should first double check with the hardware
    that it actually supports MWAIT before potentially exposing

    snapshot: Use pm_mutex for mutual exclusion
    
    We can avoid taking the BKL in snapshot_ioctl() if pm_mutex is used to prevent
    the ioctls from being executed concurrently.
    
    In addition, although it is only possible to open /dev/snapshot once, the task
    which has done that may spawn a child that will inherit the open descriptor,
    so in theory they can call snapshot_write(), snapshot_read() and
    snapshot_release() concurrently.  pm_mutex can also be used for mutual
    exclusion in such cases.

    Freezer: Introduce PF_FREEZER_NOSIG
    
    The freezer currently attempts to distinguish kernel threads from
    user space tasks by checking if their mm pointer is unset and it
    does not send fake signals to kernel threads.  However, there are
    kernel threads, mostly related to networking, that behave like
    user space tasks and may want to be sent a fake signal to be frozen.
    
    Introduce the new process flag PF_FREEZER_NOSIG that will be set
    by default for all kernel threads and make the freezer only send
    fake signals to the tasks having PF_FREEZER_NOSIG unset.  Provide
    the set_freezable_with_signal() function to be called by the kernel
    threads that want to be sent a fake signal for freezing.
    
    This patch should not change the freezer's observable behavior.

    This is apparently because some parts of ACPI, including mutexes, are not
    initialized when acpi=off is passed to the kernel.

    acer-wmi: Add debugfs file for device detection
    
    Add a debugfs file for showing the full results of the method we use to
    detect devices on WMID laptops.
    
    This should be useful in the case that a Linux user gets an Acer laptop
    with 3G support (and/ or people who enjoy ripping their wireless cards out)
    so we can get some feedback on how this value changes in these cases.
    
    (At the moment, we always enable the wireless and 3G control. In the case
    of the former, this is fairly safe. In the case of the latter though,
    trying to toggle this device if it doesn't exist on a laptop causes ACPI
    warnings/ errors).
    
    To summarise: If you have an Acer laptop with a built in 3G card, please
    report back the value from this file.

    Implemented another change for the GPE disable. We now perform a

    GPE is received during initialization (before GPE handlers are installed.)

    ACPI: fix processor throttling set error
    
    http://bugzilla.kernel.org/show_bug.cgi?id=9704
    
    When echo some invalid values to /proc/acpi/processor/*/throttling,
    there isn't any error info returned, on the contray, it sets
    throttling value to some T* successfully, obviously, this is incorrect,
    a correct way should be to let it fail and return error info.
    
    This patch fixed the aforementioned issue, it also enables
    /proc/acpi/processor/*/throttling to accept such values as 't0' and 'T0',
    it also strictly limits /proc/acpi/processor/*/throttling only to accept
     "*", "t*" and "T*", "*" is the throttling state value the processor can
    support, current, it is 0 - 7.
    
    Before applying this patch, the test result is below:

    ACPI: fix acpi fan state set error
    
    Under /proc/acpi, there is a fan control interface, a user can
    set 0 or 3 to /proc/acpi/fan/*/state, 0 denotes D0 state, 3
    denotes D3 state, but in current implementation, a user can
    set a fan to D1 state by any char excluding '1', '2' and '3'.
    
    For example:
    
    [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
    status:                  off
    [root@localhost acpi]# echo "" > /proc/acpi/fan/C31B/state
    [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
    status:                  on
    [root@localhost acpi]# echo "3" > /proc/acpi/fan/C31B/state
    [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
    status:                  off
    [root@localhost acpi]# echo "xxxxx" > /proc/acpi/fan/C31B/state
    [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
    status:                  on
    
    Obviously, such inputs as "" and "xxxxx" are invalid for fan state.
    
    This patch fixes this issue, it strictly limits fan state only to
    accept 0, 1, 2 and 3, any other inputs are invalid.
    
    Before applying this patch, the test result is:
    
    [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
    status:                  off
    [root@localhost acpi]# echo "" > /proc/acpi/fan/C31B/state
    [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
    status:                  on
    [root@localhost acpi]# echo "3" > /proc/acpi/fan/C31B/state
    [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
    status:                  off
    [root@localhost acpi]# echo "xxxxx" > /proc/acpi/fan/C31B/state
    [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
    status:                  on
    [root@localhost acpi]# echo "3" > /proc/acpi/fan/C31B/state
    [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
    status:                  off
    [root@localhost acpi]# echo "3x" > /proc/acpi/fan/C31B/state
    [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
    status:                  off
    [root@localhost acpi]# echo "-1x" > /proc/acpi/fan/C31B/state
    [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
    status:                  on

    Fujitsu-laptop update
    
    Add additional capabilities to the Fujitsu-laptop driver.
    
     * Brightness hotkey actions are sent to userspace. This can be disabled
       using a module parameter if it causes issues with models which handle
       these keys transparently in the BIOS.
    
     * Actions of additional hotkeys found on some Fujitsu models (eg: the
       suspend key and the dedicated "power on passphrase" keys) are broadcast
       to userspace.
    
     * An alternative brightness control method used by some Fujitsu models
       (for example, the S6410) is now supported, enabling software brightness
       controls on models using this method.
    
     * DMI-based module aliases are configured for the S6410 and S7020.
    
     * The current LCD brightness after booting should now be reflected in the
       standard backlight interface sysfs file (previously it was always set to
       0).  The platform brightness sysfs interface has always been fine.
    
    Thanks go to Peter Gruber who provided a significant portion of this code
    and tested various iterations of the patch on his S6410.

    misc,acpi,backlight: compal Laptop Extras
    
    This is driver for Compal Laptop: FL90/IFL90, based on MSI driver.
    
    This driver exports a few files in /sys/devices/platform/compal-laptop/:
     lcd_level - screen brightness: contains a single integer in the range 0..7 (rw)
     wlan - wlan subsystem state: contains 0 or 1 (rw)
     bluetooth - bluetooth subsystem state: contains 0 or 1 (rw)
     raw - raw value taken from embedded controller register (ro)
    
    In addition to these platform device attributes the driver registers itself
    in the Linux backlight control subsystem and is available to userspace under
    /sys/class/backlight/compal-laptop/.

    force offline the processor during hot-removal
    
    The ACPI device node for the cpu has already been unregistered
    when acpi_processor_handle_eject is called.
    Thus we should offline the cpu and continue, rather than a failure here.

    fix a deadlock issue when poking "eject" file
    
    "/sys/devices/LNXSYSTM:00/.../eject" is used to evaluate _EJx method
    and eject a device in user space.
    But system hangs when poking the "eject" file because that
    the device hot-removal code invoke the driver .remove method which will
    try to remove the "eject" file as a result.
    
    Queues the hot-removal function for deferred execution in this patch.

    Fix MIPS cross-compile problem
    
    Crosscompiling on a Fedora 9 machine running gcc 4.3.0 as its host compiler
    and gcc 3.4.6 for the mips-linux target results in the following build
    error:
    
    $ make malta_defconfig
    $ make
    cc1: error: unrecognized command line option "-fno-stack-protector"
    scripts/kconfig/conf -s arch/mips/Kconfig
    cc1: error: unrecognized command line option "-fno-stack-protector"
    
    The arch Makefile is included too late so the host compiler is feature
    tested, not the crosscompiler as intended and thus the Makefile applies
    adds -fno-stack-protector to crosscompiler's flags which fails for gcc
    3.4.6.  The bug was introduced by e06b8b98da071f7dd78fb7822991694288047df0
    in 2.6.25; 35bb5b1e0e84cfa1a8906f7e6a77f391ff315791 did add more flags
    testing before the arch Makefile inclusion.

    IDE: Report errors during drive reset back to user space
    
    Make sure that each error condition during the execution of an
    HDIO_DRIVE_RESET ioctl is actually reported to the calling process.
    Also, unify the exit path of reset_pollfunc() when returning ide_stopped
    since the need of ->port_ops->reset_poll() to be treated specially has
    vanished (way back, it seems).

    IDE: Fix HDIO_DRIVE_RESET handling
    
    Currently, the code path executing an HDIO_DRIVE_RESET ioctl is broken
    in various ways.  Most importantly, it is treated as an out of band
    request in an illegal way which may very likely lead to system lock ups.
    Use the drive's request queue to avoid this problem (and fix a locking
    issue for free along the way).

    ide: use the dma safe check for REQ_TYPE_ATA_PC
    
    This uses the dma safe check for REQ_TYPE_ATA_PC. The dma safe check
    is used for only sg requests but it should be used for other non fs
    commands.
    
    This uses blk_queue_update_dma_pad to make the intention clear though
    ide don't use the blk APIs so it doesn't change anything.

    ide: avoid DMA on the stack for REQ_TYPE_ATA_PC
    
    Some REQ_TYPE_ATA_PC commands uses the stack buffers for DMA, which
    leads to memory corruption on a non-coherent platform.
    
    With regard to alignment and padding, ide-cd has the the dma safe
    check for sg requests and REQ_TYPE_ATA_PC. This adds the stack buffer
    check to that check.

    The ad7418 driver is only used on embedded platforms where i2c

    i2c driver makes perfect sense. This lets us get rid of quirky
    detection code (these chips have no identification registers) and
    shrinks the binary driver size by 38%.

    x86/PCI: ACPI based PCI gap calculation
    
    Using ACPI to find free address space allows us to find a gap for the
    unallocated PCI resources or MMIO resources for hotplug devices within
    the BIOS allowed PCI regions.
    
    It works by evaluating the _CRS object under PCI0 looking for producer
    resources.  Then searches the e820 memory space for a gap within these
    producer resources.

    In the case of nfs_revalidate_inode(), we're only doing an attribute
    update (protected by the inode->i_lock).
    In the case of nfs_lookup(), we're instantiating a new dentry, so there
    should be no contention possible until after we call d_materialise_unique.

    NFS: Remove BKL requirement from attribute updates
    
    The main problem is dealing with inode->i_size: we need to set the
    inode->i_lock on all attribute updates, and so vmtruncate won't cut it.
    Make an NFS-private version of vmtruncate that has the necessary locking
    semantics.
    
    The result should be that the following inode attribute updates are
    protected by inode->i_lock
    	nfsi->cache_validity
    	nfsi->read_cache_jiffies
    	nfsi->attrtimeo
    	nfsi->attrtimeo_timestamp
    	nfsi->change_attr
    	nfsi->last_updated
    	nfsi->cache_change_attribute
    	nfsi->access_cache
    	nfsi->access_cache_entry_lru
    	nfsi->access_cache_inode_lru
    	nfsi->acl_access
    	nfsi->acl_default
    	nfsi->nfs_page_tree

    	inode->i_ctime
    	inode->i_nlink
    	inode->i_uid

    nfs: set correct fl_len in nlmclnt_test()
    
    fcntl(F_GETLK) on an nfs client incorrectly returns
    the values for the conflicting lock. fl_len value is
    always 1.
    If the conflicting lock is (0, 4095) the F_GETLK
    request for (1024, 10) returns (0, 1), which doesn't
    even cover the requested range, and is quite confusing.
    The fix is trivial, set fl_end from the fl_end value
    recieved from the nfs server.

    SUNRPC: Support registering IPv6 interfaces with local rpcbind daemon
    
    Introduce a new API to register RPC services on IPv6 interfaces to allow
    the NFS server and lockd to advertise on IPv6 networks.
    
    Unlike rpcb_register(), the new rpcb_v4_register() function uses rpcbind
    protocol version 4 to contact the local rpcbind daemon.  The version 4
    SET/UNSET procedures allow services to register address families besides
    AF_INET, register at specific network interfaces, and register transport
    protocols besides UDP and TCP.  All of this functionality is exposed via
    the new rpcb_v4_register() kernel API.
    
    A user-space rpcbind daemon implementation that supports version 4 of the
    rpcbind protocol is required in order to make use of this new API.
    
    Note that rpcbind version 3 is sufficient to support the new rpcbind
    facilities listed above, but most extant implementations use version 4.

    ide: remove action argument in ide_do_drive_cmd
    
    ide_do_drive_cmd is called only with ide_preempt action argument. So
    we can remove the action argument in ide_do_drive_cmd and ide_action_t
    typedef.
    
    This patch also includes two minor cleanups: 1) ide_do_drive_cmd
    always succeeds so we don't need the return value; 2) the callers use
    blk_rq_init before ide_do_drive_cmd so there is no need to initialize

    ide-scsi: replace ide_do_drive_cmd with blk_execute_rq_nowait
    
    All the callers of ide_do_drive_cmd() except for ide-scsi use
    ide_preempt action argument. This converts ide-scsi to use
    blk_execute_rq_nowait instead of ide_do_drive_cmd so that we can
    remove the action argument in ide_do_drive_cmd and ide_action_t
    typedef.

    ide: eliminate FIT() macro
    
    Replace the FIT() macro with the kernel-provided clamp_val() macro.
    
    FIT was always being called with a member of a struct ide_timing,
    which are shorts, and constant constraints for the min and max.
    
    Thus we can use clamp_val, rather than clamp_t.

    ide: disable drive interrupts in ide_driveid_update()
    
    Since ide_driveid_update() uses polling to execute the IDENTIFY DEVICE command
    but clears nIEN bit in the control register and doesn't mask the IDE interrupt,
    the latter does happen and lead to the corresponding message to appear:
    
    ide0: unexpected interrupt, status=0x58, count=1
    
    when e.g. running hdparm with option -X with a non-PCI IDE driver...

    [MIPS] IP28: switch to "normal" mode after PROM no longer needed
    
    SGI-IP28 is running in so called slow mode, when kernel is started
    from the PROM. PROM calls must be done in slow mode otherwise the
    PROM will issue an error. To get better memory performance we now
    switch to normal mode, when the PROM is no longer needed.

    [MIPS] A few cleanups in malta_int.c
    
    Both the fill_ipi_map() routine and the gic_intr_map array defined
    in arch/mips/mips-boards/malta/malta_int.c are not used outside of
    the latter file. Thus, these objects can become static. Moreover,
    these two objects are used by the MT code only, which is why this
    patch adds the appropriate ifdef.
    
    While at it, this patch removes an unnecessary preprocessing macro
    in favor of the commonly used ARRAY_SIZE.

    [MIPS] Fix asm constraints for 'ins' instructions.
    
    The third operand to 'ins' must be a constant int, not a register.
    
    [Ralf: The bug was actually intensional.  Some versions used to throw an
    error under certain circumstances for code like:
    
    static inline void f(unsigned nr, unsigned *p)
    {
    	unsigned short bit = nr & 5;
    
    	if (__builtin_constant_p(bit)) {
    		__asm__ __volatile__ ("  foo %0, %1" : "=m" (*p) : "i" (bit));
      	} else {
    		/* Do something else. */
    	}
    }
    
    because gcc was not able to figure out that the "i" constraint was possibly
    at the early stage when the constraint are getting verified.  The solution
    was using "ri" instead of "i".  The "ri" would keep gcc happy but in the
    end for code generation always the "i" constraint would be satisfied.  The
    problem afair originally appeared in the i386 io.h and also hit it's mips
    equivalent.  From there the workaround spread to many of the inline
    assembler functions.]

    Relax requirements on host controllers and only require that they do not

    upper layers should already be prepared to handle that scenario. This

    atmel-mci: Driver for Atmel on-chip MMC controllers
    
    This is a driver for the MMC controller on the AP7000 chips from
    Atmel. It should in theory work on AT91 systems too with some
    tweaking, but since the DMA interface is quite different, it's not
    entirely clear if it's worth merging this with the at91_mci driver.
    
    This driver has been around for a while in BSPs and kernel sources
    provided by Atmel, but this particular version uses the generic DMA
    Engine framework (with the slave extensions) instead of an
    avr32-only DMA controller framework.
    
    This driver can also use PIO transfers when no DMA channels are
    available, and for transfers where using DMA may be difficult or
    impractical for some reason (e.g. the DMA setup overhead is usually
    not worth it for very short transfers, and badly aligned buffers or
    lengths are difficult to handle.)
    
    Currently, the driver only support PIO transfers. DMA support has been
    split out to a separate patch to hopefully make it easier to review.
    
    The driver has been tested using mmc-block and ext3fs on several SD,
    SDHC and MMC+ cards. Reads and writes work fine, with read transfer
    rates up to 3.5 MiB/s on fast cards with debugging disabled.
    
    The driver has also been tested using the mmc_test module on the same
    cards. All tests except 7, 9, 15 and 17 succeed. The first two are
    unsupported by all the cards I have, so I don't know if the driver
    handles this correctly. The last two fail because the hardware flags a
    Data CRC Error instead of a Data Timeout error. I'm not sure how to deal
    with that.
    
    Documentation for this controller can be found in many data sheets from
    Atmel, including the AT32AP7000 data sheet which can be found here:

    mmc,sdio: helper function for transfer padding
    
    There are a lot of crappy controllers out there that cannot handle
    all the request sizes that the MMC/SD/SDIO specifications require.
    In case the card driver can pad the data to overcome the problems,
    this commit adds a helper that calculates how much that padding
    should be.
    
    A corresponding helper is also added for SDIO, but it can also deal
    with all the complexities of splitting up a large transfer efficiently.

    mmc: change .get_ro() callback semantics
    
    Now get_ro() callback must return 0/1 values for its logical states, and
    negative errno values in case of error. If particular host instance doesn't
    support RO/WP switch, it should return -ENOSYS.
    
    This patch changes some hosts in two ways:
    
    1. Now functions should be smart to not return negative values in
       "RO asserted" case (particularly gpio_ calls could return negative
       values for the outermost GPIOs).
    
       Also, board code usually passes get_ro() callbacks that directly return
       gpioreg & bit result, so at91_mci, imxmmc, pxamci and mmc_spi's get_ro()
       handlers need take special care when returning platform's values to the
       mmc core.
    
    2. In case of host instance didn't implement get_ro() callback, it should
       really return -ENOSYS and let the mmc core decide what to do about it
       (mmc core thinks the same way as the hosts, so it isn't functional
       change).

    mmc: add support for card-detection polling
    
    Some hosts (and boards that use mmc_spi) do not use interrupts on the CD
    line, so they can't trigger mmc_detect_change. We want to poll the card
    and see if there was a change. 1 second poll interval seems resonable.

    mlx4_core: Use MOD_STAT_CFG command to get minimal page size
    
    There was a bug in some versions of the mlx4 driver in
    mlx4_alloc_fmr(), which hardcoded the minimum acceptable page_shift to
    be 12.  However, new ConnectX firmware can support a minimum
    page_shift of 9 (log_pg_sz of 9 returned by QUERY_DEV_LIM) -- so with
    old drivers, ib_fmr_alloc() would fail for ULPs using the device
    minimum when creating FMRs.
    
    To preserve firmware compatibility with released mlx4 drivers, the
    firmware will continue to return 12 as before for log_page_sz in
    QUERY_DEV_CAP for these drivers.  However, to enable new drivers to
    take advantage of the available smaller page size, the mlx4 driver now
    first sets the log_pg_sz to the device minimum by setting a
    log_page_sz value to 0 via the MOD_STAT_CFG command and then reading
    the real minimum via QUERY_DEV_CAP.

    RDMA/cma: Simplify locking needed for serialization of callbacks
    
    The RDMA CM has some logic in place to make sure that callbacks on a
    given CM ID are delivered to the consumer in a serialized manner.
    Specifically it has code to protect against a device removal racing
    with a running callback function.
    
    This patch simplifies this logic by using a mutex per ID instead of a
    wait queue and atomic variable.  This means that cma_disable_remove()
    now is more properly named to cma_disable_callback(), and
    cma_enable_remove() can now be removed because it just would become a
    trivial wrapper around mutex_unlock().

    RDMA/cxgb3: Fixes for zero STag
    
    Handling the zero STag in receive work request requires some extra
    logic in the driver:
    
     - Only set the QP_PRIV bit for kernel mode QPs.
    
    - Add a zero STag build function for recv wrs. The uP needs a PBL
      allocated and passed down in the recv WR so it can construct a HW
      PBL for the zero STag S/G entries.  Note: we need to place a few
      restrictions on zero STag usage because of this:
    
      1) all SGEs in a recv WR must either be zero STag or not.  No mixing.
    
      2) an individual SGE length cannot exceed 128MB for a zero-stag SGE.
         This should be OK since it's not really practical to allocate
         such a large chunk of pinned contiguous DMA mapped memory.
    
    - Add an optimized non-zero-STag recv wr format for kernel users.
      This is needed to optimize both zero and non-zero STag cracking in
      the recv path for kernel users.
    
     - Remove the iwch_ prefix from the static build functions.
    
     - Bump required FW version.

    IB/ipath: Use IEEE OUI for vendor_id reported by ibv_query_device()
    
    The IB spe. for SubnGet(NodeInfo) and query HCA says that the vendor
    ID field should be the IEEE OUI assigned to the vendor.  The ipath
    driver was returning the PCI vendor ID instead.  This will affect
    applications which call ibv_query_device().  The old value was
    0x001fc1 or 0x001077, the new value is 0x001175.
    
    The vendor ID doesn't appear to be exported via /sys so that should
    reduce possible compatibility issues.  I'm only aware of Open MPI as a
    major application which depends on this change, and they have made

    IPoIB: Refresh paths instead of flushing them on SM change events
    
    The patch tries to solve the problem of device going down and paths being
    flushed on an SM change event. The method is to mark the paths as candidates for
    refresh (by setting the new valid flag to 0), and wait for an ARP
    probe a new path record query.
    
    The solution requires a different and less intrusive handling of SM
    change event. For that, the second argument of the flush function
    changes its meaning from a boolean flag to a level.  In most cases, SM
    failover doesn't cause LID change so traffic won't stop.  In the rare
    cases of LID change, the remote host (the one that hadn't changed its
    LID) will lose connectivity until paths are refreshed. This is no
    worse than the current state.  In fact, preventing the device from
    going down saves packets that otherwise would be lost.

    This patch also adds a creation flag for QPs,
    IB_QP_CREATE_MULTICAST_BLOCK_LOOPBACK, which when set means that
    multicast sends from the QP to a group that the QP is attached to will
    not be looped back to the QP's receive queue.  This can be used to

    RDMA/core: Add iWARP protocol statistics attributes in sysfs
    
    This patch adds a sysfs attribute group called "proto_stats" under
    /sys/class/infiniband/$device/ and populates this group with protocol
    statistics if they exist for a given device.  Currently, only iWARP
    stats are defined, but the code is designed to allow InfiniBand
    protocol stats if they become available.  These stats are per-device
    and more importantly -not- per port.
    
    Details:
    
    - Add union rdma_protocol_stats in ib_verbs.h.  This union allows
      defining transport-specific stats.  Currently only iwarp stats are
      defined.
    
    - Add struct iw_protocol_stats to define the current set of iwarp
      protocol stats.
    
    - Add new ib_device method called get_proto_stats() to return protocol
      statistics.
    
    - Add logic in core/sysfs.c to create iwarp protocol stats attributes
      if the device is an RNIC and has a get_proto_stats() method.

    IPoIB/cm: Fix racy use of receive WR/SGL in ipoib_cm_post_receive_nonsrq()
    
    For devices that don't support SRQs, ipoib_cm_post_receive_nonsrq() is
    called from both ipoib_cm_handle_rx_wc() and ipoib_cm_nonsrq_init_rx(),
    and these two callers are not synchronized against each other.
    However, ipoib_cm_post_receive_nonsrq() always reuses the same receive
    work request and scatter list structures, so multiple callers can end
    up stepping on each other, which leads to posting garbled work
    requests.
    
    Fix this by having the caller pass in the ib_recv_wr and ib_sge
    structures to use, and allocating new local structures in
    ipoib_cm_nonsrq_init_rx().

    RDMA/core: Add memory management extensions support
    
    This patch adds support for the IB "base memory management extension"
    (BMME) and the equivalent iWARP operations (which the iWARP verbs
    mandates all devices must implement).  The new operations are:
    
     - Allocate an ib_mr for use in fast register work requests.
    
     - Allocate/free a physical buffer lists for use in fast register work
       requests.  This allows device drivers to allocate this memory as
       needed for use in posting send requests (eg via dma_alloc_coherent).
    
     - New send queue work requests:
       * send with remote invalidate
       * fast register memory region
       * local invalidate memory region
       * RDMA read with invalidate local memory region (iWARP only)
    
    Consumer interface details:
    
     - A new device capability flag IB_DEVICE_MEM_MGT_EXTENSIONS is added
       to indicate device support for these features.
    
     - New send work request opcodes IB_WR_FAST_REG_MR, IB_WR_LOCAL_INV,
       IB_WR_RDMA_READ_WITH_INV are added.
    
     - A new consumer API function, ib_alloc_mr() is added to allocate
       fast register memory regions.
    
     - New consumer API functions, ib_alloc_fast_reg_page_list() and
       ib_free_fast_reg_page_list() are added to allocate and free
       device-specific memory for fast registration page lists.
    
     - A new consumer API function, ib_update_fast_reg_key(), is added to
       allow the key portion of the R_Key and L_Key of a fast registration
       MR to be updated.  Consumers call this if desired before posting
       a IB_WR_FAST_REG_MR work request.
    
    Consumers can use this as follows:
    
     - MR is allocated with ib_alloc_mr().
    
     - Page list memory is allocated with ib_alloc_fast_reg_page_list().
    
     - MR R_Key/L_Key "key" field is updated with ib_update_fast_reg_key().
    
     - MR made VALID and bound to a specific page list via
       ib_post_send(IB_WR_FAST_REG_MR)
    
     - MR made INVALID via ib_post_send(IB_WR_LOCAL_INV),
       ib_post_send(IB_WR_RDMA_READ_WITH_INV) or an incoming send with
       invalidate operation.
    
     - MR is deallocated with ib_dereg_mr()
    
     - page lists dealloced via ib_free_fast_reg_page_list().
    
    Applications can allocate a fast register MR once, and then can
    repeatedly bind the MR to different physical block lists (PBLs) via
    posting work requests to a send queue (SQ).  For each outstanding
    MR-to-PBL binding in the SQ pipe, a fast_reg_page_list needs to be
    allocated (the fast_reg_page_list is owned by the low-level driver
    from the consumer posting a work request until the request completes).
    Thus pipelining can be achieved while still allowing device-specific
    page_list processing.
    
    The 32-bit fast register memory key/STag is composed of a 24-bit index
    and an 8-bit key.  The application can change the key each time it
    fast registers thus allowing more control over the peer's use of the
    key/STag (ie it can effectively be changed each time the rkey is
    rebound to a page list).

    IPoIB: Copy small received SKBs in connected mode
    
    The connected mode implementation in the IPoIB driver has a large
    overhead in the way SKBs are handled in the receive flow.  It usually
    allocates an SKB with as big as was used in the currently received SKB
    and moves unused fragments from the old SKB to the new one. This
    involves a loop on all the remaining fragments and incurs overhead on
    the CPU.  This patch, for small SKBs, allocates an SKB just large
    enough to contain the received data and copies to it the data from the
    received SKB.  The newly allocated SKB is passed to the stack and the
    old SKB is reposted.

    With this patch I get both send and receive at ~315 mbps.
    
    The reason that send performance actually slows down is as follows:
    When using this patch, the overhead of the CPU for handling RX packets
    is dramatically reduced.  As a result, we do not experience RNR NAK
    messages from the receiver which cause the connection to be closed and
    reopened again; when the patch is not used, the receiver cannot handle
    the packets fast enough so there is less time to post new buffers and
    hence the mentioned RNR NACKs.  So what happens is that the
    application *thinks* it posted a certain number of packets for
    transmission but these packets are flushed and do not really get
    transmitted.  Since the connection gets opened and closed many times,
    each time netperf gets the CPU time that otherwise would have been
    given to IPoIB to actually transmit the packets.  This can be verified
    when looking at the port counters -- the output of ifconfig and the
    oputput of netperf (this is for the case without the patch):
    
        tx packets

        port counter:   1,543,996
        ifconfig:       1,581,426

    IB/mlx4: Optimize QP stamping
    
    The idea is that for QPs with fixed size work requests (eg selective
    signaling QPs), before stamping the WQE, we read the value of the DS
    field, which gives the effective size of the descriptor as used in the
    previous post.  Then we stamp only that area, since the rest of the
    descriptor is already stamped.
    
    When initializing the send queue buffer, make sure the DS field is
    initialized to the max descriptor size so that the subsequent stamping
    will be done on the entire descriptor area.

    IB/sa: Fail requests made while creating new SM AH
    
    This patch solves a race that occurs after an event occurs that causes
    the SA query module to flush its SM address handle (AH).  When SM AH
    becomes invalid and needs an update it is handled by the global
    workqueue.  On the other hand this event is also handled in the IPoIB
    driver by queuing work in the ipoib_workqueue that does multicast
    joins.  Although queuing is in the right order, it is done to 2
    different workqueues and so there is no guarantee that the first to be
    queued is the first to be executed.
    
    This causes a problem because IPoIB may end up sending an request to
    the old SM, which will take a long time to time out (since the old SM
    is gone); this leads to a much longer than necessary interruption in
    multicast traffer.
    
    The patch sets the SA query module's SM AH to NULL when the event
    occurs, and until update_sm_ah() is done, any request that needs sm_ah
    fails with -EAGAIN return status.
    
    For consumers, the patch doesn't make things worse.  Before the patch,
    MADs are sent to the wrong SM so the request gets lost.  Consumers can
    be improved if they examine the return code and respond to EAGAIN
    properly but even without an improvement the situation is not getting
    worse.

    powerpc: Add PPC_FEATURE_PSERIES_PERFMON_COMPAT
    
    Background from Maynard Johnson:
    As of POWER6, a set of 32 common events is defined that must be
    supported on all future POWER processors.  The main impetus for this
    compat set is the need to support partition migration, especially from
    processor P(n) to processor P(n+1), where performance software that's
    running in the new partition may not be knowledgeable about processor
    P(n+1).  If a performance tool determines it does not support the
    physical processor, but is told (via the
    PPC_FEATURE_PSERIES_PERFMON_COMPAT bit) that the processor supports
    the notion of the PMU compat set, then the performance tool can
    surface just those events to the user of the tool.
    
    PPC_FEATURE_PSERIES_PERFMON_COMPAT indicates that the PMU supports at
    least this basic subset of events which is compatible across POWER
    processor lines.

    configfs: Allow ->make_item() and ->make_group() to return detailed errors.
    
    The configfs operations ->make_item() and ->make_group() currently
    return a new item/group.  A return of NULL signifies an error.  Because
    of this, -ENOMEM is the only return code bubbled up the stack.
    
    Multiple folks have requested the ability to return specific error codes
    when these operations fail.  This patch adds that ability by changing the
    ->make_item/group() ops to return an int.
    
    Also updated are the in-kernel users of configfs.

    configfs: Fix failing mkdir() making racing rmdir() fail
    
    When fixing the rename() vs rmdir() deadlock, we stopped locking default groups'
    inodes in configfs_detach_prep(), letting racing mkdir() in default groups
    proceed concurrently. This enables races like below happen, which leads to a
    failing mkdir() making rmdir() fail, despite the group to remove having no
    user-created directory under it in the end.
    
    	process A: 			process B:
    	/* PWD=A/B */
    	mkdir("C")
    	  make_item("C")
    	  attach_group("C")
    					rmdir("A")
    					  detach_prep("A")
    					    detach_prep("B")
    					      error because of "C"
    					  return -ENOTEMPTY
    	    attach_group("C/D")
    	      error (eg -ENOMEM)
    	  return -ENOMEM
    
    This patch prevents such scenarii by making rmdir() wait as long as
    detach_prep() fails because a racing mkdir() is in the middle of attach_group().
    To achieve this, mkdir() sets a flag CONFIGFS_USET_IN_MKDIR in parent's
    configfs_dirent before calling attach_group(), and clears the flag once
    attach_group() is done. detach_prep() fails with -EAGAIN whenever the flag is
    hit and returns the guilty inode's mutex so that rmdir() can wait on it.

    configfs: Fix deadlock with racing rmdir() and rename()
    
    This patch fixes the deadlock between racing sys_rename() and configfs_rmdir().
    
    The idea is to avoid locking i_mutexes of default groups in
    configfs_detach_prep(), and rely instead on the new configfs_dirent_lock to
    protect against configfs_dirent's linkage mutations. To ensure that an mkdir()
    racing with rmdir() will not create new items in a to-be-removed default group,
    we make configfs_new_dirent() check for the CONFIGFS_USET_DROPPING flag right
    before linking the new dirent, and return error if the flag is set. This makes
    racing mkdir()/symlink()/dir_open() fail in places where errors could already
    happen, resp. in (attach_item()|attach_group())/create_link()/new_dirent().
    
    configfs_depend() remains safe since it locks all the path from configfs root,
    and is thus mutually exclusive with rmdir().
    
    An advantage of this is that now detach_groups() unconditionnaly takes the
    default groups i_mutex, which makes it more consistent with populate_groups().

    Symlinks to a config_item are listed under its configfs_dirent s_links, but the
    list mutations are not protected by any common lock.
    
    This patch uses the configfs_dirent_lock spinlock to add the necessary
    protection.
    
    Note: we should also protect the list_empty() test in configfs_detach_prep() but
    1/ the lock should not be released immediately because nothing would prevent the
    list from being filled after a successful list_empty() test, making the problem
    tricky,
    2/ this will be solved by the rmdir() vs rename() deadlock bugfix.

    configfs: Introduce configfs_dirent_lock
    
    This patch introduces configfs_dirent_lock spinlock to protect configfs_dirent
    traversals against linkage mutations (add/del/move). This will allow
    configfs_detach_prep() to avoid locking i_mutexes.
    
    Locking rules for configfs_dirent linkage mutations are the same plus the
    requirement of taking configfs_dirent_lock. For configfs_dirent walking, one can
    either take appropriate i_mutex as before, or take configfs_dirent_lock.
    
    The spinlock could actually be a mutex, but the critical sections are either
    O(1) or should not be too long (default groups walking in last patch).
    
    ChangeLog:
      - Clarify the comment on configfs_dirent_lock usage
      - Move sd->s_element init before linking the new dirent
      - In lseek(), do not release configfs_dirent_lock before the dirent is
        relinked.

    ocfs2: Don't snprintf() without a format.
    
    Some system files are per-slot.  Their names include the slot number.
    ocfs2_sprintf_system_inode_name() uses the system inode definitions to
    fill in the slot number with snprintf().
    
    For global system files, there is no node number, and the name was
    printed as a format with no arguments.  -Wformat-nonliteral and
    -Wformat-security don't like this.  Instead, use a static "%s" format
    and the name as the argument.

    i2c: Add detection capability to new-style drivers
    
    Add a mechanism to let new-style i2c drivers optionally autodetect
    devices they would support on selected buses and ask i2c-core to
    instantiate them. This is a replacement for legacy i2c drivers, much
    cleaner.
    
    Where drivers had to implement both a legacy i2c_driver and a
    new-style i2c_driver so far, this mechanism makes it possible to get
    rid of the legacy i2c_driver and implement both enumerated and
    detected device support with just one (new-style) i2c_driver.
    
    Here is a quick conversion guide for these drivers, step by step:
    
    * Delete the legacy driver definition, registration and removal.
      Delete the attach_adapter and detach_client methods of the legacy
      driver.
    
    * Change the prototype of the legacy detect function from
        static int foo_detect(struct i2c_adapter *adapter, int address, int kind);
      to
        static int foo_detect(struct i2c_client *client, int kind,
        			  struct i2c_board_info *info);
    
    * Set the new-style driver detect callback to this new function, and
      set its address_data to &addr_data (addr_data is generally provided
      by I2C_CLIENT_INSMOD.)
    
    * Add the appropriate class to the new-style driver. This is
      typically the class the legacy attach_adapter method was checking
      for. Class checking is now mandatory (done by i2c-core.) See
      <linux/i2c.h> for the list of available classes.
    
    * Remove the i2c_client allocation and freeing from the detect
      function. A pre-allocated client is now handed to you by i2c-core,
      and is freed automatically.
    
    * Make the detect function fill the type field of the i2c_board_info
      structure it was passed as a parameter, and return 0, on success. If
      the detection fails, return -ENODEV.

    i2c: Call client_unregister for new-style devices too
    
    We call adapter->client_register for both legacy and new-style i2c
    devices, however we only call adapter->client_unregister for legacy
    drivers. This doesn't make much sense. Usually, drivers will undo
    in client_unregister what they did in client_register, so we should
    call neither or both for every given i2c device.
    
    In order to ease the transition from legacy to new-style devices, it
    seems preferable to actually call both.

     The standard rtc-m41t80.c driver cannot be used with the SWARM as it is,
    because the board does not provide setup information for the I2C core.
    As a result the bus and the address to probe for the M41T80 chip is not
    known.
    
     Here is a set of changes that fix the problem:
    
    1. swarm-i2c.c -- SWARM I2C board setup, currently for the M41T80 chip on
       the bus #1 only (there is a MAX6654 temperature sensor on the bus #0
       which may be added in the future if we have a driver for that chip).
    
    2. The i2c-sibyte.c BCM1250A SMBus controller driver now registers its
       buses as numbered so that board setup is correctly applied.

    i2c-i801: Fix handling of error conditions
    
    Move the check of pre-transaction and post-transaction conditions to
    separate functions, and adjust them a bit. Having dedicated functions
    for that ensures that errors are handled in a consistent way.
    
    Bit HOST_BUSY of the status register is read-only, so writing to it is
    certainly not going to clear it. If this bit is set then we simply
    don't want to start the transaction, as it means that somebody else
    (ACPI, SMM?) is already using the controller.

    i2c/eeprom: Fall back to SMBus read word transactions
    
    When I2C block reads are not supported by the underlying adapter, use
    SMBus read word transactions instead of consecutive byte reads.
    Reasons for this change are:
    
    * The consecutive byte read approach is not safe on multi-master buses.
    
    * While consecutive byte reads have less overhead if you only count the
      bytes on the bus, it takes more than twice as many transactions as
      with SMBus read word transactions, and each transaction has a cost:
      taking and releasing the adapter mutex, and for polling drivers,
      waiting for the transaction to complete.
    
    This change yields a significant performance boost at HZ=250 with
    EEPROMs on an Intel 82801 bus (basically twice as fast.)
    
    SMBus read word transactions are widely supported so I don't expect
    compatibility issues.

    i2c: Let bus drivers add SPD to their class
    
    Let general purpose I2C/SMBus bus drivers add SPD to their class. Once
    this is done, we will be able to tell the eeprom driver to only probe
    for SPD EEPROMs and similar on these buses.
    
    Note that I took a conservative approach here, adding I2C_CLASS_SPD to
    many drivers that have no idea whether they can host SPD EEPROMs or not.
    This is to make sure that the eeprom driver doesn't stop probing buses
    where SPD EEPROMs or equivalent live.
    
    So, bus driver maintainers and users should feel free to remove the SPD
    class from drivers those buses never have SPD EEPROMs or they don't
    want the eeprom driver to bind to them. Likewise, feel free to add the
    SPD class to any bus driver I might have missed.

    * Drop useless masks on the 7-bit address and the R/W bit.
    * Reject block transaction requests with an invalid block length.

    fault/error code usage in the I2C stack.  It turns out that

    i2c-nforce2: Add support for multiplexing on the Tyan S4985
    
    Just like the Tyan S4882, the S4985 uses a multiplexer to give access
    to all 16 memory module SPD EEPROMs. This specific i2c-nforce2-s4985
    driver adds support for this. It is heavily based on the older
    i2c-amd756-s4882 driver.
    
    As more mainboards will use multiplexer chips, we will have to find a
    way to support them without having to write a new specfic driver for
    each. The recent changes to the i2c subsystem should help us, and the
    new gpio subsystem might help, too.

    i2c-davinci: Remove useless IVR read
    
    Interrupts are enabled at the point where the DAVINCI_I2C_IVR_REG is read,
    so unless an interrupt happened just at that moment, no interrupt would be
    pending. Even though documentation implies you should do this, I see no
    reason. If slave support is added, this read would cause a hard to
    reproduce bug.

    AHCI: Remove an unnecessary flush from ahci_qc_issue
    
    In an I/O heavy workload (IOZone), ahci_qc_issue is the second-highest
    consumer of CPU cycles.  Removing the flush gets us approximately 10%
    bandwidth improvement.  I believe this to be because the CPU can start
    queueing the next request instead of waiting for the readl() to flush the
    writes to the device.  The flush isn't necessary because we're using a
    'queue' metaphor; we don't guarantee the command has got to the device,
    nor do we need to guarantee the command has got to the controller.

    AHCI: speed up resume
    
    During resume, sleep 1 second to wait for the HBA reset
    to finish is a waste of time.
    
    According to the AHCI 1.2 spec,
    We should poll the HOST_CTL register,
    and return error if the host reset is not
    finished within 1 second.
    
    Test results show that the HBA reset can be done quickly(in usecs).

    libata: improve EH internal command timeout handling
    
    ATA_TMOUT_INTERNAL which was 30secs were used for all internal
    commands which is way too long when something goes wrong.  This patch
    implements command type based stepped timeouts.  Different command
    types can use different timeouts and each command type can use
    different timeout values after timeouts.
    
    ie. the initial timeout is set to a value which should cover most of
    the cases but not too long so that run away cases don't delay things
    too much.  After the first try times out, the second try can use
    longer timeout and if that one times out too, it can go for full 30sec
    timeout.
    
    IDENTIFYs use 5s - 10s - 30s timeout and all other commands use 5s -
    10s timeouts.
    
    This patch significantly cuts down the needed time to handle failure
    cases while still allowing libata to work with nut job devices through
    retries.

    libata: improve EH retry delay handling
    
    EH retries were delayed by 5 seconds to ensure that resets don't occur
    back-to-back.  However, this 5 second delay is superflous or excessive
    in many cases.  For example, after IDENTIFY times out, there's no
    reason to wait five more seconds before retrying.
    
    This patch adds ehc->last_reset timestamp and record the timestamp for
    the last reset trial or success and uses it to space resets by
    ATA_EH_RESET_COOL_DOWN which is 5 secs and removes unconditional 5 sec
    sleeps.
    
    As this change makes inter-try waits often shorter and they're
    redundant in nature, this patch also removes the "retrying..."
    messages.
    
    While at it, convert explicit rounding up division to DIV_ROUND_UP().
    
    This change speeds up EH in many cases w/o sacrificing robustness.

    libata: consistently use msecs for time durations
    
    libata has been using mix of jiffies and msecs for time druations.
    This is getting confusing.  As writing sub HZ values in jiffies is
    PITA and msecs_to_jiffies() can't be used as initializer, unify unit
    for all time durations to msecs.  So, durations are in msecs and
    deadlines are in jiffies.  ata_deadline() is added to compute deadline
    from a start time and duration in msecs.
    
    While at it, drop now superflous _msec suffix from arguments and
    rename @timeout to @deadline if it represents a fixed point in time
    rather than duration.

    x86, suspend, acpi: enter Big Real Mode
    
    The explanation for recent video BIOS suspend quirk failures is that
    the VESA BIOS expects to be entered in Big Real Mode (*.limit = 0xffffffff)
    instead of ordinary Real Mode (*.limit = 0xffff).
    
    This patch changes the segment descriptors to Big Real Mode instead.
    
    The segment descriptor registers (what Intel calls "segment cache") is
    always active.  The only thing that changes based on CR0.PE is how it is
    *loaded* and the interpretation of the CS flags.
    
    The segment descriptor registers contain of the following sub-registers:
    selector (the "visible" part), base, limit and flags.  In protected mode
    or long mode, they are loaded from descriptors (or fs.base or gs.base can
    be manipulated directly in long mode.)  In real mode, the only thing
    changed by a segment register load is the selector and the base, where the
    base <- selector << 4.  In particular, *the limit and the flags are not
    changed*.
    
    As far as the handling of the CS flags: a code segment cannot be writable
    in protected mode, whereas it is "just another segment" in real mode, so
    there is some kind of quirk that kicks in for this when CR0.PE <- 0.  I'm
    not sure if this is accomplished by actually changing the cs.flags register
    or just changing the interpretation; it might be something that is
    CPU-specific.  In particular, the Transmeta CPUs had an explicit "CS is
    writable if you're in real mode" override, so even if you had loaded CS
    with an execute-only segment it'd be writable (but not readable!) on return
    to real mode.  I'm not at all sure if that is how other CPUs behave.

    firewire: don't respond to broadcast write requests
    
    Contrary to a comment in the source, request->ack of a broadcast write
    request can be ACK_PENDING.  Hence the existing check is insufficient.
    
    Debug dmesg before:
    AR spd 0 tl 00, ffc0 -> ffff, ack_pending , QW req, fffff0000234 = ffffffff
    AT spd 0 tl 00, ffff -> ffc0, ack_complete, W resp
    And the requesting node (linux1394) reports an unsolicited response.

    firewire: clean up fw_card reference counting
    
    This is a functionally equivalent replacement of the current reference
    counting of struct fw_card instances.  It only converts it to common
    idioms as suggested by Kristian Høgsberg:
      - struct kref replaces atomic_t as the counter.
      - wait_for_completion is used to wait for all card users to complete.
    
    BTW, it may make sense to count card->flush_timer and card->work as
    card users too.

    scsi: sd: optionally set power condition in START STOP UNIT
    
    Adds a new scsi_device flag, start_stop_pwr_cond:  If enabled, the sd
    driver will not send plain START STOP UNIT commands but ones with the
    power condition field set to 3 (standby) or 1 (active) respectively.
    
    Some FireWire disk firmwares do not stop the motor if power condition is
    zero.  Or worse, they become unresponsive after a START STOP UNIT with
    power condition = 0 and start = 0.
    
    http://lkml.org/lkml/2008/4/29/704
    
    This patch only adds the necessary code to sd_mod but doesn't activate
    it.  Follow-up patches to the FireWire drivers will add detection of
    affected devices and enable the code for them.
    
    I did not add power condition values to scsi_error.c::scsi_eh_try_stu()
    for now.  The three firmwares which suffer from above mentioned problems
    do not need START STOP UNIT in the error handler, and they are not
    adversely affected by START STOP UNIT with power condition = 0 and start
    = 1 (like scsi_eh_try_stu() sends it if scsi_device.allow_restart is
    enabled).

    [S390] sclp_tty: Fix scheduling while atomic bug.
    
    Finally fixes a possible scheduling while in atomic context bug. The driver
    used to wait on a waitqueue if no empty buffer was available. This could
    lead to a deadlock if the driver was called from non-schedulable context.
    So fix this. The write operation may fail now. It returns the number of
    characters accepted. put_char will never fail, since it writes characters
    to an intermediate buffer which gets flushed as soon as it is full.
    That means the driver now can busy wait if something is in the intermediate
    buffer and a write_string operation follows. Seems to be an acceptable
    compromise, since that shouldn't happen too often.

    [S390] sclp_tty: remove ioctl interface.
    
    After all we came to the conclusion that this interface doesn't make any
    sense. Besides that the ioctl number used was never registered, the header
    file isn't exported, and we doubt there is even a single user.
    So remove this interface, since it eases maintenance.

    alloc_bootmem and related functions never return NULL and always return a

    [S390] Add sched.h include to asm-s390/pgtable.h.
    
    Some macros in pgtable.h access members from struct task_struct.
    Currently always works since sched.h seems always to be included
    before asm/pgtable.h. Unfortunately that is not anymore true with
    Jeremy Fitzhardinge's ptep_modify_prot transaction abstraction patch.
    So fix this.

    [S390] Extra Kernel Parameters via VMPARM
    
    Now it is possible to specify additional kernel parameters on the IPL
    command line using the IPL PARM option.
    If the Linux system is already running, the new reipl sysfs attribute
    'parm' can be used to change kernel parameters for the next reboot.
    Examples:
      IPL    C PARM dasd=1234 root=/dev/dasda1

    [S390] ap: Use high-resolution timer for polling
    
    The ap poll mechanism is converted to use a high-resolution timer for
    polling. This allows more specific polling. With this a new sysfs
    attribute is introduced to specify the polling rate in nanoseconds.

    This patch adds a driver for subchannels of type chsc.
    
    A device /dev/chsc is created which may be used to issue ioctls to:
    - obtain information about the machine's I/O configuration
    - dynamically change the machine's I/O configuration via

    [S390] initrd vs bss section clearing.
    
    In case the initrd is located within the bss section it will be
    overwritten when the section is cleared. To prevent this just move
    the initrd right behind the bss section if it starts within the
    section.
    The current code already moves the initrd if the bootmem allocator
    bitmap would overwrite it. With this patch we should be safe against
    initrd corruptions.

    Both arguments are size_t so does not affect correctness.  This callsite is

    SELinux: allow fstype unknown to policy to use xattrs if present
    
    Currently if a FS is mounted for which SELinux policy does not define an
    fs_use_* that FS will either be genfs labeled or not labeled at all.
    This decision is based on the existence of a genfscon rule in policy and
    is irrespective of the capabilities of the filesystem itself.  This
    patch allows the kernel to check if the filesystem supports security
    xattrs and if so will use those if there is no fs_use_* rule in policy.
    An fstype with a no fs_use_* rule but with a genfs rule will use xattrs
    if available and will follow the genfs rule.
    
    This can be particularly interesting for things like ecryptfs which
    actually overlays a real underlying FS.  If we define excryptfs in
    policy to use xattrs we will likely get this wrong at times, so with
    this path we just don't need to define it!
    
    Overlay ecryptfs on top of NFS with no xattr support:
    SELinux: initialized (dev ecryptfs, type ecryptfs), uses genfs_contexts
    Overlay ecryptfs on top of ext4 with xattr support:
    SELinux: initialized (dev ecryptfs, type ecryptfs), uses xattr
    
    It is also useful as the kernel adds new FS we don't need to add them in
    policy if they support xattrs and that is how we want to handle them.

    security_load_policy we are covered and can safely just drop this one.

    SELinux: fix off by 1 reference of class_to_string in context_struct_compute_av
    
    The class_to_string array is referenced by tclass.  My code mistakenly
    was using tclass - 1.  If the proceeding class is a userspace class
    rather than kernel class this may cause a denial/EINVAL even if unknown
    handling is set to allow.  The bug shouldn't be allowing excess
    privileges since those are given based on the contents of another array
    which should be correctly referenced.
    
    At this point in time its pretty unlikely this is going to cause
    problems.  The most recently added kernel classes which could be
    affected are association, dccp_socket, and peer.  Its pretty unlikely
    any policy with handle_unknown=allow doesn't have association and
    dccp_socket undefined (they've been around longer than unknown handling)
    and peer is conditionalized on a policy cap which should only be defined
    if that class exists in policy.

    selinux: fix endianness bug in network node address handling
    
    Fix an endianness bug in the handling of network node addresses by
    SELinux.  This yields no change on little endian hardware but fixes
    the incorrect handling on big endian hardware.  The network node
    addresses are stored in network order in memory by checkpolicy, not in
    cpu/host order, and thus should not have cpu_to_le32/le32_to_cpu
    conversions applied upon policy write/read unlike other data in the
    policy.
    
    Bug reported by John Weeks of Sun, who noticed that binary policy
    files built from the same policy source on x86 and sparc differed and
    tracked it down to the ipv4 address handling in checkpolicy.

    selinux: simplify ioctl checking
    
    Simplify and improve the robustness of the SELinux ioctl checking by
    using the "access mode" bits of the ioctl command to determine the
    permission check rather than dealing with individual command values.
    This removes any knowledge of specific ioctl commands from SELinux
    and follows the same guidance we gave to Smack earlier.

    SELinux: enable processes with mac_admin to get the raw inode contexts
    
    Enable processes with CAP_MAC_ADMIN + mac_admin permission in policy
    to get undefined contexts on inodes.  This extends the support for
    deferred mapping of security contexts in order to permit restorecon
    and similar programs to see the raw file contexts unknown to the
    system policy in order to check them.

    Security: split proc ptrace checking into read vs. attach
    
    Enable security modules to distinguish reading of process state via
    proc from full ptrace access by renaming ptrace_may_attach to
    ptrace_may_access and adding a mode argument indicating whether only
    read access or full attach access is requested.  This allows security
    modules to permit access to reading process state without granting
    full ptrace access.  The base DAC/capability checking remains unchanged.
    
    Read access to /proc/pid/mem continues to apply a full ptrace attach
    check since check_mem_permission() already requires the current task
    to already be ptracing the target.  The other ptrace checks within
    proc for elements like environ, maps, and fds are changed to pass the
    read mode instead of attach.
    
    In the SELinux case, we model such reading of process state as a
    reading of a proc file labeled with the target process' label.  This
    enables SELinux policy to permit such reading of process state without
    permitting control or manipulation of the target process, as there are
    a number of cases where programs probe for such information via proc
    but do not need to be able to control the target (e.g. procps,
    lsof, PolicyKit, ConsoleKit).  At present we have to choose between
    allowing full ptrace in policy (more permissive than required/desired)
    or breaking functionality (or in some cases just silencing the denials
    via dontaudit rules but this can hide genuine attacks).
    
    This version of the patch incorporates comments from Casey Schaufler
    (change/replace existing ptrace_may_attach interface, pass access
    mode), and Chris Wright (provide greater consistency in the checking).
    
    Note that like their predecessors __ptrace_may_attach and
    ptrace_may_attach, the __ptrace_may_access and ptrace_may_access
    interfaces use different return value conventions from each other (0
    or -errno vs. 1 or 0).  I retained this difference to avoid any
    changes to the caller logic but made the difference clearer by
    changing the latter interface to return a bool rather than an int and
    by adding a comment about it to ptrace.h for any future callers.

    selinux: support deferred mapping of contexts
    
    Introduce SELinux support for deferred mapping of security contexts in
    the SID table upon policy reload, and use this support for inode
    security contexts when the context is not yet valid under the current
    policy.  Only processes with CAP_MAC_ADMIN + mac_admin permission in
    policy can set undefined security contexts on inodes.  Inodes with
    such undefined contexts are treated as having the unlabeled context
    until the context becomes valid upon a policy reload that defines the
    context.  Context invalidation upon policy reload also uses this
    support to save the context information in the SID table and later
    recover it upon a subsequent policy reload that defines the context
    again.
    
    This support is to enable package managers and similar programs to set
    down file contexts unknown to the system policy at the time the file
    is created in order to better support placing loadable policy modules
    in packages and to support build systems that need to create images of
    different distro releases with different policies w/o requiring all of
    the contexts to be defined or legal in the build host policy.
    
    With this patch applied, the following sequence is possible, although
    in practice it is recommended that this permission only be allowed to
    specific program domains such as the package manager.

    drm: reorganise drm tree to be more future proof.
    
    With the coming of kernel based modesetting and the memory manager stuff,
    the everything in one directory approach was getting very ugly and
    starting to be unmanageable.
    
    This restructures the drm along the lines of other kernel components.
    
    It creates a drivers/gpu/drm directory and moves the hw drivers into
    subdirectores. It moves the includes into an include/drm, and
    sets up the unifdef for the userspace headers we should be exporting.

    rcu classic: update qlen when cpu offline
    
    When callbacks are moved from offline cpu to this cpu,
    the qlen field of this rdp should be updated.
    
    [ Paul E. McKenney: ]
    
    The effect of this bug would be for force_quiescent_state() to be invoked
    when it should not and vice versa -- wasting cycles in the first case
    and letting RCU callbacks remain piled up in the second case.  The bug
    is thus "benign" in that it does not result in premature grace-period
    termination, but should of course be fixed nonetheless.
    
    Preemption is disabled by the caller's get_cpu_var(), so we are guaranteed
    to remain on the same CPU, as required.  The local_irq_disable() is indeed
    needed, otherwise, an interrupt might invoke call_rcu() or call_rcu_bh(),
    which could cause that interrupt's increment of ->qlen to be lost.

    Current device tree is only bare bones.  This patch adds nodes to make
    it a complete tree for the MPC5121ads.
    
    Added nodes include:
        mbx      - opengl coprocessor
        nfc      - nand flash controller
        cpld-pic - on board cpld
        rtc

        pscfifo  - psc fifo configuration
        dma
        pci
    
    Fix typo in header changing MDS to ADS.
    
    Add a compatible property of the form "fsl,mpc5121-..."
    to nodes missing one.
    
    Changed localbus compatible to fsl,mpc5121-localbus, this does
    not break anything because the only code that uses it finds it
    via the node name, not compatible.

    On MPC5200 the PCI target control register (PCITCR) @ MBAR + 0xD6C is
    initialized with only bit 7 (Latrule disable) set. The 8-Bit write
    combine timer (Bits 24..31) should be also set to a reasonable value
    _greater zero_ (0x08 = default) since setting it to 0x00 leads to
    _very poor_ performance as a PCI target since external burst won't be
    possible at all.
    
    Setting the WCT to 0x08 (cache-line size) leads to good overall perfomance.

    [SCSI] fix locking in host use of blk_plug_device()
    
    scsi_lib.c:scsi_host_queue_ready() plugs the device with incorrect
    locking.  It should actually have the queue lock held, but it's
    holding the host lock.  Fix this by eliminating the call.  The host
    ready has no need to plug the queue because if it returns 0 in
    scsi_request_function control transfers to not_ready which acquires
    the queue lock and plugs the device if its at zero depth.

    [SCSI] libiscsi, iscsi_tcp, ib_iser: fix setting of can_queue with old tools.
    
    This patch fixes two bugs that are related.
    
    1. Old tools did not set can_queue/cmds_max. This patch modifies
    libiscsi so that when we add the host we catch this and set it
    to the default.
    
    2. iscsi_tcp thought that the scsi command that was passed to
    the eh functions needed a iscsi_cmd_task allocated for it. It
    only needed a mgmt task, and now it does not matter since it
    all comes from the same pool and libiscsi handles this for the
    drivers. ib_iser had copied iscsi_tcp's code and set can_queue
    to its max - 1 to handle this. So this patch removes the max -1,
    and just sets it to the max.

    Seen:
    
    	kernel BUG at arch/i386/lib/usercopy.c:872
    
    under a 2.6.18-8.el5 kernel. Traced it to a garbage-in/garbage-out
    ioctl condition in the aacraid driver.
    
    Adaptec's special ioctl scb passthrough needs to check the validity of
    the individual scatter gather count fields to the maximum the adapter
    supports. Doing so will have the side effect of preventing
    copy_from_user() from bugging out while populating the dma buffers.
    This is a hardening effort, issue was triggered by an errant version
    of the management tools and thus the BUG should not be seen in the
    field.

    The recv lock was defined so the iscsi layer could block
    the recv path from processing IO during recovery. It
    turns out iser just set a lock to that pointer which was pointless.
    
    We now disconnect the transport connection before doing recovery
    so we do not need the recv lock. For iscsi_tcp we still stop
    the recv path incase older tools are being used.
    
    This patch also has iscsi_itt_to_ctask user grab the session lock
    and has the caller access the task with the lock or get a ref
    to it in case the target is broken and sends a tmf success response
    then sends data or a response for the command that was supposed to
    be affected bty the tmf.

    [SCSI] iscsi class: Add session initiatorname and ifacename sysfs attrs.
    
    This adds two new attrs used for creating initiator ports and
    binding sessions to hardware.
    
    The session level initiatorname:
    
    Since bnx2i does a scsi_host per host device, we need to add the
    iface initiator port settings on the session, so we can create
    multiple initiator ports (each with different inames) per device/scsi_host.
    
    The current iname reflects that qla4xxx can have one iname per hba, and we are
    allocating a host per session for software. The iname on the host will
    remain so we can export and set the hba level qla4xxx setting.
    
    The ifacename attr:
    
    To bind a session to a some peice of hardware in userspace we maintain
    some mappings, but during boot or iscsid restart (iscsid contains the user
    space part of the driver) we need to be able to figure out which of those
    host mappings abstractions maps to certain sessions. This patch adds
    a ifacename attr, which userspace can set to id the host side of the
    endpoint across pivot_roots and iscsid restarts.

    [SCSI] iser: Modify iser to take a iscsi_endpoint struct in ep callouts and session setup
    
    This hooks iser into the iscsi endpoint code. Previously it handled the
    lookup and allocation. This has been made generic so bnx2i and iser can
    share it. It also allows us to pass iser the leading conn's ep, so we
    know the ib_deivce being used and can set it as the scsi_host's parent.
    And that allows scsi-ml to set the dma_mask based on those values.

    call the ep_disconnect callback, which will halt
    all recv IO, before calling the stop_conn callback so
    we do not have to worry about the conn->recv_lock and
    suspend rx field. iser just needs to stop the send side
    from accessing the ib conn.

    x86_64: fix delayed signals
    
    On three of the several paths in entry_64.S that call
    do_notify_resume() on the way back to user mode, we fail to properly
    check again for newly-arrived work that requires another call to
    do_notify_resume() before going to user mode.  These paths set the
    mask to check only _TIF_NEED_RESCHED, but this is wrong.  The other
    paths that lead to do_notify_resume() do this correctly already, and
    entry_32.S does it correctly in all cases.
    
    All paths back to user mode have to check all the _TIF_WORK_MASK
    flags at the last possible stage, with interrupts disabled.
    Otherwise, we miss any flags (TIF_SIGPENDING for example) that were
    set any time after we entered do_notify_resume().  More work flags
    can be set (or left set) synchronously inside do_notify_resume(), as
    TIF_SIGPENDING can be, or asynchronously by interrupts or other CPUs
    (which then send an asynchronous interrupt).
    
    There are many different scenarios that could hit this bug, most of
    them races.  The simplest one to demonstrate does not require any
    race: when one signal has done handler setup at the check before
    returning from a syscall, and there is another signal pending that
    should be handled.  The second signal's handler should interrupt the
    first signal handler before it actually starts (so the interrupted PC
    is still at the handler's entry point).  Instead, it runs away until
    the next kernel entry (next syscall, tick, etc).
    
    This test behaves correctly on 32-bit kernels, and fails on 64-bit
    (either 32-bit or 64-bit test binary).  With this fix, it works.

    ext4: do not set extents feature from the kernel
    
    We've talked for a while about getting rid of any feature-
    setting from the kernel; this gets rid of the code which would
    set the INCOMPAT_EXTENTS flag on the first file write when mounted
    as ext4[dev].
    
    With this patch, if the extents feature is not already set on disk,
    then mounting as ext4 will fall back to noextents with a warning,
    and if -o extents is explicitly requested, the mount will fail,
    also with warning.

    ext4: Don't allow nonextenst mount option for large filesystem
    
    The block mapped inode format can address only blocks within 2**32. This
    causes a number of issues, the biggest of which is that the block
    allocator needs to be taught that certain inodes can not utilize block
    numbers > 2**32.  So until this is fixed, it is simplest to fail
    mounting of file systems with more than 2**32 blocks if the -o noextents
    option is given.

    ext4: delayed allocation i_blocks fix for stat
    
    Right now i_blocks is not getting updated until the blocks are actually
    allocaed on disk.  This means with delayed allocation, right after files
    are copied, "ls -sF" shoes the file as taking 0 blocks on disk.  "du"
    also shows the files taking zero space, which is highly confusing to the
    user.
    
    Since delayed allocation already keeps track of per-inode total
    number of blocks that are subject to delayed allocation, this patch fix
    this by using that to adjust the value returned by stat(2). When real
    block allocation is done, the i_blocks will get updated. Since the
    reserved blocks for delayed allocation will be decreased, this will be
    keep value returned by stat(2) consistent.

    ext4: fix delalloc i_disksize early update issue
    
    Ext4_da_write_end() used walk_page_buffers() with a callback function of
    ext4_bh_unmapped_or_delay() to check if it extended the file size
    without allocating any blocks (since in this case i_disksize needs to be
    updated).  However, this is didn't work proprely because the buffer head
    has not been marked dirty yet --- this is done later in
    block_commit_write() --- which caused ext4_bh_unmapped_or_delay() to
    always return false.
    
    In addition, walk_page_buffers() checks all of the buffer heads covering
    the page, and the only buffer_head that should be checked is the one
    covering the end of the write.  Otherwise, given a 1k blocksize
    filesystem and a 4k page size, the buffer head covering the first 1k
    stripe of the file could be unmapped (because it was a sparse file), and
    the second or third buffer_head covering that page could be mapped, and
    using walk_page_buffers() would fail in this case since it would stop at
    the first unmapped buffer_head and return true.
    
    The core problem is that walk_page_buffers() was intended to do work in
    a callback function, and a non-zero return value indicated a failure,
    which termined the walk of the buffer heads covering the page.  It was
    not intended to be used with a boolean function, such as
    ext4_bh_unmapped_or_delay().
    
    Add addtional fix from Aneesh to protect i_disksize update rave with truncate.

    ext4: Handle page without buffers in ext4_*_writepage()
    
    It can happen that buffers are removed from the page before it gets
    marked dirty and then is passed to writepage().  In writepage() we just
    initialize the buffers and check whether they are mapped and non
    delay. If they are mapped and non delay we write the page. Otherwise we
    mark them dirty.  With this change we don't do block allocation at all
    in ext4_*_write_page.
    
    writepage() can get called under many condition and with a locking order
    of journal_start -> lock_page, we should not try to allocate blocks in
    writepage() which get called after taking page lock.  writepage() can
    get called via shrink_page_list even with a journal handle which was
    created for doing inode update.  For example when doing
    ext4_da_write_begin we create a journal handle with credit 1 expecting a
    i_disksize update for the inode. But ext4_da_write_begin can cause
    shrink_page_list via _grab_page_cache. So having a valid handle via
    ext4_journal_current_handle is not a guarantee that we can use the
    handle for block allocation in writepage, since we shouldn't be using
    credits that had been reserved for other updates.  That it could result
    in we running out of credits when we update inodes.

    ext4: Add ordered mode support for delalloc
    
    This provides a new ordered mode implementation which gets rid of using
    buffer heads to enforce the ordering between metadata change with the
    related data chage.  Instead, in the new ordering mode, it keeps track
    of all of the inodes touched by each transaction on a list, and when
    that transaction is committed, it flushes all of the dirty pages for
    those inodes.  In addition, the new ordered mode reverses the lock
    ordering of the page lock and transaction lock, which provides easier
    support for delayed allocation.

    mm: Add range_cont mode for writeback
    
    Filesystems like ext4 needs to start a new transaction in
    the writepages for block allocation. This happens with delayed
    allocation and there is limit to how many credits we can request
    from the journal layer. So we call write_cache_pages multiple
    times with wbc->nr_to_write set to the maximum possible value
    limitted by the max journal credits available.
    
    Add a new mode to writeback that enables us to handle this
    behaviour. In the new mode we update the wbc->range_start
    to point to the new offset to be written. Next call to
    call to write_cache_pages will start writeout from specified
    range_start offset. In the new mode we also limit writing
    to the specified wbc->range_end.

    heads for data buffers in the ordered mode.  With the changes, during

    transaction commit. This can cause a deadlock with the locking order
    page_lock -> jbd2_journal_start, since the jbd2_journal_start can wait
    for the journal_commit to happen and the journal_commit now needs to
    take the page lock. To avoid this dead lock reverse the locking order.

    ext4: Set journal pointer to NULL when journal is released
    
    Set sbi->s_journal to NULL after we call journal_destroy(). This
    will be later needed because after journal_destroy() is called,
    ext4_clear_inode() can still be called for some inodes (e.g. root
    inode) and we'll need to detect there that journal doesn't exists

    ext4: Use inode preallocation with -o noextents
    
    When mballoc is enabled, block allocation for old block-based
    files are allocated using mballoc allocator instead of old
    block-based allocator. The old ext3 block reservation is turned
    off when mballoc is turned on.
    
    However, the in-core preallocation is not enabled for block-based/
    non-extent based file block allocation. This result in performance
    regression, as now we don't have "reservation" ore in-core preallocation
    to prevent interleaved fragmentation in multiple writes workload.
    
    This patch fix this by enable per inode in-core preallocation
    for non extent files when mballoc is used.

    jbd2: fix race between jbd2_journal_try_to_free_buffers() and jbd2 commit transaction
    
    journal_try_to_free_buffers() could race with jbd commit transaction
    when the later is holding the buffer reference while waiting for the
    data buffer to flush to disk. If the caller of
    journal_try_to_free_buffers() request tries hard to release the buffers,
    it will treat the failure as error and return back to the caller. We
    have seen the directo IO failed due to this race.  Some of the caller of
    releasepage() also expecting the buffer to be dropped when passed with
    GFP_KERNEL mask to the releasepage()->journal_try_to_free_buffers().
    
    With this patch, if the caller is passing the GFP_KERNEL to indicating
    this call could wait, in case of try_to_free_buffers() failed, let's
    waiting for journal_commit_transaction() to finish commit the current
    committing transaction , then try to free those buffers again with
    journal locked.

    ext4: New inode allocation for FLEX_BG meta-data groups.
    
    This patch mostly controls the way inode are allocated in order to
    make ialloc aware of flex_bg block group grouping.  It achieves this
    by bypassing the Orlov allocator when block group meta-data are packed
    toghether through mke2fs.  Since the impact on the block allocator is
    minimal, this patch should have little or no effect on other block
    allocation algorithms. By controlling the inode allocation, it can
    basically control where the initial search for new block begins and
    thus indirectly manipulate the block allocator.
    
    This allocator favors data and meta-data locality so the disk will
    gradually be filled from block group zero upward.  This helps improve
    performance by reducing seek time.  Since the group of inode tables
    within one flex_bg are treated as one giant inode table, uninitialized
    block groups would not need to partially initialize as many inode
    table as with Orlov which would help fsck time as the filesystem usage
    goes up.

    ext4: Fix mb_find_next_bit not to return larger than max
    
    Some architectures implement ext4_find_next_bit and
    ext4_find_next_zero_bit in such a way that they return
    greater than max for some input values. Make sure
    mb_find_next_bit and mb_find_next_zero_bit return the
    right values.
    
    On 2.6.25 we have include/asm-x86/bitops_32.h
    static inline unsigned find_first_bit(const unsigned long *addr, unsigned size)
    {
    	unsigned x = 0;
    
    	while (x < size) {
    		unsigned long val = *addr++;
    		if (val)
    			return __ffs(val) + x;
    		x += (sizeof(*addr)<<3);
    	}
    	return x;
    }
    
    This can return value greater than size.

    ext4: validate directory entry data before use
    
    ext4_dx_find_entry uses ext4_next_entry without verifying that the entry is
    valid. If its rec_len == 0 this causes an infinite loop. Refactor the loop
    to check the validity of entries before checking whether they match and
    moving onto the next one.
    
    There are other uses of ext4_next_entry in this file which also look
    problematic. They should be reviewed and fixed if/when we have a test-case
    that triggers them.

    x86: I/O APIC: Never configure IRQ2
    
    There is no such entity as ISA IRQ2.  The ACPI spec does not make it
    explicitly clear, but does not preclude it either -- all it says is ISA
    legacy interrupts are identity mapped by default (subject to overrides),
    but it does not state whether IRQ2 exists or not.  As a result if there is
    no IRQ0 override, then IRQ2 is normally initialised as an ISA interrupt,
    which implies an edge-triggered line, which is unmasked by default as this
    is what we do for edge-triggered I/O APIC interrupts so as not to miss an
    edge.
    
    To the best of my knowledge it is useless, as IRQ2 has not been in use
    since the PC/AT as back then it was taken by the 8259A cascade interrupt
    to the slave, with the line position in the slot rerouted to newly-created
    IRQ9.  No device could thus make use of this line with the pair of 8259A
    chips.  Now in theory INTIN2 of the I/O APIC may be usable, but the
    interrupt of the device wired to it would not be available in the PIC mode
    at all, so I seriously doubt if anybody decided to reuse it for a regular
    device.
    
    However there are two common uses of INTIN2.  One is for IRQ0, with an
    ACPI interrupt override (or its equivalent in the MP table).  But in this
    case IRQ2 is gone entirely with INTIN0 left vacant.  The other one is for
    an 8959A ExtINTA cascade.  In this case IRQ0 goes to INTIN0 and if ACPI is
    used INTIN2 is assumed to be IRQ2 (there is no override and ACPI has no
    way to report ExtINTA interrupts).  This is where a problem happens.
    
    The problem is INTIN2 is configured as a native APIC interrupt, with a
    vector assigned and the mask cleared.  And the line may indeed get active
    and inject interrupts if the master 8959A has its timer interrupt enabled
    (it might happen for other interrupts too, but they are normally masked in
    the process of rerouting them to the I/O APIC).  There are two cases where
    it will happen:
    
    * When the I/O APIC NMI watchdog is enabled.  This is actually a misnomer
      as the watchdog pulses are delivered through the 8259A to the LINT0
      inputs of all the local APICs in the system.  The implication is the
      output of the master 8259A goes high and low repeatedly, signalling
      interrupts to INTIN2 which is enabled too!
    
      [The origin of the name is I think for a brief period during the
      development we had a capability in our code to configure the watchdog to
      use an I/O APIC input; that would be INTIN2 in this scenario.]
    
    * When the native route of IRQ0 via INTIN0 fails for whatever reason -- as
      it happens with the system considered here.  In this scenario the timer
      pulse is delivered through the 8259A to LINT0 input of the local APIC of
      the bootstrap processor, quite similarly to how is done for the watchdog
      described above.  The result is, again, INTIN2 receives these pulses
      too.  Rafael's system used to escape this scenario, because an incorrect
      IRQ0 override would occupy INTIN2 and prevent it from being unmasked.
    
    My conclusion is IRQ2 should be excluded from configuration in all the
    cases and the current exception for ACPI systems should be lifted.  The
    reason being the exception not only being useless, but harmful as well.

    x86: L-APIC: Always fully configure IRQ0
    
    Unlike the 32-bit one, the 64-bit variation of the LVT0 setup code for
    the "8259A Virtual Wire" through the local APIC timer configuration does
    not fully configure the relevant irq_chip structure.  Instead it relies on
    the preceding I/O APIC code to have set it up, which does not happen if
    the I/O APIC variants have not been tried.
    
    The patch includes corresponding changes to the 32-bit variation too
    which make them both the same, barring a small syntactic difference
    involving sequence of functions in the source.  That should work as an aid
    with the upcoming merge.

    |     x86: remove open-coded save/load segment operations
    |
    |     This removes a pile of buggy open-coded implementations of savesegment
    |     and loadsegment.
    
    after some more bisection of this patch itself, it turns out that what
    makes the difference are the savesegment() changes to __switch_to().
    
    Taking a look at this portion of arch/x86/kernel/process_64.o revealed
    this crutial difference:
    
    | good:    99c:       8c e0                   mov    %fs,%eax
    |          99e:       89 45 cc                mov    %eax,-0x34(%rbp)
    |
    | bad:     99c:       8c 65 cc                mov    %fs,-0x34(%rbp)
    
    which is due to:
    
    |                 unsigned fsindex;
    | -               asm volatile("movl %%fs,%0" : "=r" (fsindex));
    | +               savesegment(fs, fsindex);
    
    savesegment() is implemented as:
    
     #define savesegment(seg, value)                                \
              asm("mov %%" #seg ",%0":"=rm" (value) : : "memory")
    
    note the "m" modifier - it allows GCC to generate the segment move
    into a memory operand as well.
    
    But regarding segment operands there's a subtle detail in the x86
    instruction set: the above 16-bit moves are zero-extend, but only
    if it goes to a register.
    
    If it goes to a memory operand, -0x34(%rbp) in the above case, there's
    no zero-extend to 32-bit and the instruction will only save 16 bits
    instead of the intended 32-bit.
    
    The other 16 bits is random data - which can cause problems when that
    value is used later on.
    
    The solution is to only allow segment operands to go to registers.
    This fix allows my test-system to boot up without crashing.

    sched_clock: and multiplier for TSC to gtod drift
    
    The sched_clock code currently tries to keep all CPU clocks of all CPUS
    somewhat in sync. At every clock tick it records the gtod clock and
    uses that and jiffies and the TSC to calculate a CPU clock that tries to
    stay in sync with all the other CPUs.
    
    ftrace depends heavily on this timer and it detects when this timer
    "jumps".  One problem is that the TSC and the gtod also drift.
    When the TSC is 0.1% faster or slower than the gtod it is very noticeable
    in ftrace. To help compensate for this, I've added a multiplier that
    tries to keep the CPU clock updating at the same rate as the gtod.
    
    I've tried various ways to get it to be in sync and this ended up being
    the most reliable. At every scheduler tick we calculate the new multiplier:
    
      multi = delta_gtod / delta_TSC
    
    This means we perform a 64 bit divide at the tick (once a HZ). A shift
    is used to handle the accuracy.
    
    Other methods that failed due to dynamic HZ are:
    
    (not used)  multi += (gtod - tsc) / delta_gtod
    (not used)  multi += (gtod - (last_tsc + delta_tsc)) / delta_gtod
    
    as well as other variants.
    
    This code still allows for a slight drift between TSC and gtod, but
    it keeps the damage down to a minimum.

    sched_clock: record TSC after gtod
    
    To read the gtod we need to grab the xtime lock for read. Reading the gtod
    before the TSC can cause a bigger gab if the xtime lock is contended.
    
    This patch simply reverses the order to read the TSC after the gtod.
    The locking in the reading of the gtod handles any barriers one might
    think is needed.

    sched_clock: only update deltas with local reads.
    
    Reading the CPU clock should try to stay accurate within the CPU.
    By reading the CPU clock from another CPU and updating the deltas can
    cause unneeded jumps when reading from the local CPU.
    
    This patch changes the code to update the last read TSC only when read
    from the local CPU.

    sched_clock: fix calculation of other CPU
    
    The algorithm to calculate the 'now' of another CPU is not correct.
    At each scheduler tick, each CPU records the last sched_clock and
    gtod (tick_raw and tick_gtod respectively). If the TSC is somewhat the
    same in speed between two clocks the algorithm would be:
    
      tick_gtod1 + (now1 - tick_raw1) = tick_gtod2 + (now2 - tick_raw2)
    
    To calculate now2 we would have:
    
      now2 = (tick_gtod1 - tick_gtod2) + (tick_raw2 - tick_raw1) + now1
    
    Currently the algorithm is:
    
      now2 = (tick_gtod1 - tick_gtod2) + (tick_raw1 - tick_raw2) + now1
    
    This solves most of the rest of the issues I've had with timestamps in
    ftace.

    sched_clock: stop maximum check on NO HZ
    
    Working with ftrace I would get large jumps of 11 millisecs or more with
    the clock tracer. This killed the latencing timings of ftrace and also
    caused the irqoff self tests to fail.
    
    What was happening is with NO_HZ the idle would stop the jiffy counter and
    before the jiffy counter was updated the sched_clock would have a bad
    delta jiffies to compare with the gtod with the maximum.
    
    The jiffies would stop and the last sched_tick would record the last gtod.
    On wakeup, the sched clock update would compare the gtod + delta jiffies
    (which would be zero) and compare it to the TSC. The TSC would have
    correctly (with a stable TSC) moved forward several jiffies. But because the
    jiffies has not been updated yet the clock would be prevented from moving
    forward because it would appear that the TSC jumped too far ahead.
    
    The clock would then virtually stop, until the jiffies are updated. Then
    the next sched clock update would see that the clock was very much behind
    since the delta jiffies is now correct. This would then jump the clock
    forward by several jiffies.
    
    This caused ftrace to report several milliseconds of interrupts off
    latency at every resume from NO_HZ idle.
    
    This patch adds hooks into the nohz code to disable the checking of the
    maximum clock update when nohz is in effect. It resumes the max check
    when nohz has updated the jiffies again.

    sched_clock: widen the max and min time
    
    With keeping the max and min sched time within one jiffy of the gtod clock
    was too tight. Just before a schedule tick the max could easily be hit, as
    well as just after a schedule_tick the min could be hit. This caused the
    clock to jump around by a jiffy.
    
    This patch widens the minimum to
       last gtod + (delta_jiffies ? delta_jiffies - 1 : 0) * TICK_NSECS
    
    and the maximum to
        last gtod + (2 + delta_jiffies) * TICK_NSECS
    
    This keeps the minum to gtod or if one jiffy less than delta jiffies
    and the maxim 2 jiffies ahead of gtod. This may cause unstable TSCs to be
    a bit more sporadic, but it helps keep a clock with a stable TSC working well.

    sched_clock: record from last tick
    
    The sched_clock code tries to keep within the gtod time by one tick (jiffy).
    The current code mistakenly keeps track of the delta jiffies between
    updates of the clock, where the the delta is used to compare with the
    number of jiffies that have past since an update of the gtod. The gtod is
    updated at each schedule tick not each sched_clock update. After one
    jiffy passes the clock is updated fine. But the delta is taken from the
    last update so if the next update happens before the next tick the delta
    jiffies used will be incorrect.
    
    This patch changes the code to check the delta of jiffies between ticks
    and not updates to match the comparison of the updates with the gtod.

    ftrace: separate out the function enabled variable
    
    Currently the function tracer uses the global tracer_enabled variable that
    is used to keep track if the tracer is enabled or not. The function tracing
    startup needs to be separated out, otherwise the internal happenings of

    This patch creates a ftrace_function_enabled variable to all the starting
    of the function traces to happen after everything has been started.

    ftrace: move sched_switch enable after markers
    
    We have two markers now that are enabled on sched_switch. One that records
    the context switching and the other that records task wake ups. Currently
    we enable the tracing first and then set the markers. This causes some
    confusing traces:
    
    # tracer: sched_switch
    #
    #           TASK-PID   CPU#    TIMESTAMP  FUNCTION
    #              | |      |          |         |
           trace-cmd-3973  [00]   115.834817:   3973:120:R   +     3:  0:S
           trace-cmd-3973  [01]   115.834910:   3973:120:R   +     6:  0:S
           trace-cmd-3973  [02]   115.834910:   3973:120:R   +     9:  0:S
           trace-cmd-3973  [03]   115.834910:   3973:120:R   +    12:  0:S
           trace-cmd-3973  [02]   115.834910:   3973:120:R   +     9:  0:S
              <idle>-0     [02]   115.834910:      0:140:R ==>  3973:120:R
    
    Here we see that trace-cmd with PID 3973 wakes up task 9 but the next line
    shows the idle task doing a context switch to task 3973.
    
    Enabling the tracing to _after_ the markers are set creates a much saner
    output:
    
    # tracer: sched_switch
    #
    #           TASK-PID   CPU#    TIMESTAMP  FUNCTION
    #              | |      |          |         |
              <idle>-0     [02]  7922.634225:      0:140:R ==>  4790:120:R
           trace-cmd-4789  [03]  7922.634225:      0:140:R   +  4790:120:R

      ...
    
    which rules make sure that various instrumentation and debugging
    facilities are disabled for code that might end up in a VDSO - such as
    the TSC code.

    nohz: don't stop idle tick if softirqs are pending.
    
    In case a cpu goes idle but softirqs are pending only an error message is
    printed to the console. It may take a very long time until the pending
    softirqs will finally be executed. Worst case would be a hanging system.
    
    With this patch the timer tick just continues and the softirqs will be
    executed after the next interrupt. Still a delay but better than a
    hanging system.
    
    Currently we have at least two device drivers on s390 which under certain
    circumstances schedule a tasklet from process context. This is a reason
    why we can end up with pending softirqs when going idle. Fixing these
    drivers seems to be non-trivial.
    However there is no question that the drivers should be fixed.
    This patch shouldn't be considered as a bug fix. It just is intended to
    keep a system running even if device drivers are buggy.

    [GFS2] Replace rgrp "recent list" with mru list
    
    This patch removes the "recent list" which is used during allocation
    and replaces it with the (already existing) mru list used during
    deletion. The "recent list" was not a true mru list leading to a number
    of inefficiencies including a "next" function which made scanning the
    list an order N^2 operation wrt to the number of list elements.
    
    This should increase allocation performance with large numbers of rgrps.
    Its also a useful preparation and cleanup before some further changes
    which are planned in this area.

    firmware: convert Ambassador ATM driver to request_firmware()
    
    Since it had various regions to be loaded to separate addresses, and it
    wanted to do them in fairly small chunks anyway, switch it to use the
    new ihex code. Encode the start address in the first record.

    ihex: Add support for long records to ihex2fw.c
    
    Some drivers could do with using records like Intel HEX, but with each
    record being larger than 256 bytes. This has been possible in the binary
    representation (struct ihex_binrec) in the kernel since the beginning --
    at least of the the current version of history. But we haven't been able
    to represent that in the .HEX files which get converted to .fw files.
    
    This adds a '-w' option to ihex2fw to make it interpret the first _two_
    bytes of each line as the record length, instead of only one byte. And
    adds makefile rules for %.H16->%.fw which use that.

    ihex.h: binary representation of ihex records
    
    Some devices need their firmware as a set of {address, len, data...}
    records in some specific order rather than a simple blob.
    
    The normal way of doing this kind of thing is 'ihex', which is a text
    format and not entirely suitable for use in the kernel.
    
    This provides a binary representation which is very similar, but much
    more compact -- and a helper routine to skip to the next record,
    because the alignment constraints mean that everybody will screw it up
    for themselves otherwise.
    
    Also a helper function which can verify that a 'struct firmware'
    contains a valid set of ihex records, and that following them won't run
    off the end of the loaded data.

    firmware: Add CONFIG_FIRMWARE_IN_KERNEL option.
    
    This will control whether we build firmware into the kernel image for
    _every_ driver which we convert to request_firmware(), to avoid a
    proliferation of 'CONFIG_XXX_FIRMWARE' options for each one.
    
    Default to 'y' for now, which is the wrong thing to do but people seem
    to be insisting on it and refusing to even review patches until it's
    done. And it does preserve the existing behaviour for built-in drivers.

    firmware: allow firmware files to be built into kernel image
    
    Some drivers have their own hacks to bypass the kernel's firmware loader
    and build their firmware into the kernel; this renders those unnecessary.
    
    Other drivers don't use the firmware loader at all, because they always
    want the firmware to be available. This allows them to start using the
    firmware loader.
    
    A third set of drivers already use the firmware loader, but can't be
    used without help from userspace, which sometimes requires an initrd.
    This allows them to work in a static kernel.

    maestro3: treat firmware data as const
    
    The maestro3 driver is byte-swapping its firmware to be host-endian in
    advance, when it doesn't seem to be necessary -- we could just use
    le16_to_cpu() as we load it.
    
    Doing that means that we need to switch the in-tree firmware to be
    little-endian too.
    
    Take the least intrusive way of doing this, which is to switch the
    existing snd_m3_convert_from_le() function to convert _to_ little-endian
    instead, and use it on the in-tree firmware instead of the loaded
    firmware. It's a bit suboptimal but doesn't matter much right now
    because we're about to remove the special cases for the in-tree version
    anyway.

    crypto: hash - Fixed digest size check
    
    The digest size check on hash algorithms is incorrect.  It's
    perfectly valid for hash algorithms to have a digest length
    longer than their block size.  For example crc32c has a block
    size of 1 and a digest size of 4.  Rather than having it lie
    about its block size, this patch fixes the checks to do what
    they really should which is to bound the digest size so that
    code placing the digest on the stack continue to work.
    
    HMAC however still needs to check this as it's only defined
    for such algorithms.

    [CRYPTO] tcrypt: Add self test for des3_ebe cipher operating in cbc mode
    
    Patch to add checking  of DES3 test vectors using CBC mode.  FIPS-140-2
    compliance mandates that any supported mode of operation must include a self
    test.  This satisfies that requirement for cbc(des3_ede).  The included test
    vector was generated by me using openssl.  Key/IV was generated with the
    following command:
    
    	openssl enc -des_ede_cbc -P
    
    input and output values were generated by repeating the string "Too many
    secrets" a few times over, truncating it to 128 bytes, and encrypting it with
    openssl using the aformentioned key.  Tested successfully by myself

    Move command descriptor setup to seperate function as preparation
    for the following DMA setup fixes.
    
    Note 1: also fix a harmless typo while moving it: sa_idx is initialized
    	to dma->resi instead of dma->cmdi.
    
    Note 2: errors from command descriptor setup are not propagated back,
    	anymore, they can't be handled anyway and all conditions leading
    	to errors should be checked earlier.

    [HIFN]: Fix data alignment checks
    
    The check for misalignment of the scatterlist data has two bugs:
    
    - the source buffer doesn't need to be aligned at all
    - the destination buffer and its size needs to be aligned to a multiple
      of 4, not to the crypto alg blocksize
    
    Introduce symbolic constant for destination buffer alignment requirements,
    use it instead of the crypto alg blocksize and remove the unnecessary
    checks for source buffer alignment and change cra_alignmask to zero.

    x86, AMD IOMMU: clean up Kconfig entry
    
    AMD_IOMMU should depend on IOMMU_HELPER since they are the IOMMU
    helper functions. SWIOTLB requires IOMMU_HELPER so declaring that
    AMD_IOMMU depends on SWIOTLB properly fixes the problems.

    x86: clean up iommu.h and gart.h
    
    This remove lots of duplications in iommu.h and gart.h.
    
    The end result of this patch is:
    
    - iommu.h is a header file for everyone related with IOMMUs.
    
    - gart.h is the private header file. Only pci-gart_64.c and its friends
      include it.

    Fix a const pointer usage warning in the Digigram VX soundcard driver.  A
    const pointer is being passed to copy_from_user() to load the firmware into.
    This is okay in this case because the function has allocated the firmware
    struct itself, but the const qualifier is part of the firmware struct - so the
    patch casts the const away.

    NFS: Allow either strict or sloppy mount option parsing
    
    The kernel's NFS client mount option parser currently doesn't allow
    unrecognized or incorrect mount options.  This prevents misspellings or
    incorrectly specified mount options from possibly causing silent data
    corruption.
    
    However, NFS mount options are not standardized, so different operating
    systems can use differently spelled mount options to support similar
    features, or can support mount options which no other operating system
    supports.
    
    "Sloppy" mount option parsing, which allows the parser to ignore any
    option it doesn't recognize, is needed to support automounters that often
    use maps that are shared between heterogenous operating systems.
    
    The legacy mount command ignores the validity of the values of mount
    options entirely, except for the "sec=" and "proto=" options.  If an
    incorrect value is specified, the out-of-range value is passed to the
    kernel; if a value is specified that contains non-numeric characters,
    it appears as though the legacy mount command sets that option to zero
    (probably incorrect behavior in general).
    
    In any case, this sets a precedent which we will partially follow for
    the kernel mount option parser:
    
    	+ if "sloppy" is not set, the parser will be strict about both
    	  unrecognized options (same as legacy) and invalid option
    	  values (stricter than legacy)
    
    	+ if "sloppy" is set, the parser will ignore unrecognized
    	  options and invalid option values (same as legacy)
    
    An "invalid" option value in this case means that either the type
    (integer, short, or string) or sign (for integer values) of the specified
    value is incorrect.
    
    This patch does two things: it changes the NFS client's mount option
    parsing loop so that it parses the whole string instead of failing at
    the first unrecognized option or invalid option value.  An unrecognized
    option or an invalid option value cause the option to be skipped.
    
    Then, the patch adds a "sloppy" mount option that allows the parsing
    to succeed anyway if there were any problems during parsing.  When
    parsing a set of options is complete, if there are errors and "sloppy"
    was specified, return success anyway.  Otherwise, only return success
    if there are no errors.

    Set the default security flavor when we set the other mount option

    NFS: Set security flavor default for NFSv2/3 mounts like other defaults
    
    Set the default security flavor when we set the other mount option default
    values.  After this change, only the legacy user-space mount path needs to
    set the NFS_MOUNT_SECFLAVOUR flag.

    SUNRPC: Use only rpcbind v2 for AF_INET requests
    
    Some server vendors support the higher versions of rpcbind only for
    AF_INET6.  The kernel doesn't need to use v3 or v4 for AF_INET anyway,
    so change the kernel's rpcbind client to query AF_INET servers over
    rpcbind v2 only.
    
    This has a few interesting benefits:
    
    1. If the rpcbind request is going over TCP, and the server doesn't
       support rpcbind versions 3 or 4, the client reduces by two the number
       of ephemeral ports left in TIME_WAIT for each rpcbind request.  This
       will help during NFS mount storms.
    
    2. The rpcbind interaction with servers that don't support rpcbind
       versions 3 or 4 will use less network traffic.  Also helpful
       during mount storms.
    
    3. We can eliminate the kernel build option that controls whether the
       kernel's rpcbind client uses rpcbind version 3 and 4 for AF_INET
       servers.  Less complicated kernel configuration...

    NFS: handle interface identifiers in incoming IPv6 addresses
    
    Add support in the kernel NFS client's address parser for interface
    identifiers.
    
    IPv6 link-local addresses require an additional "interface identifier",
    which is a network device name or an integer that indexes the array of
    local network interfaces.  They are suffixed to the address with a '%'.
    For example:
    
    	fe80::215:c5ff:fe3b:e1b2%2
    
    indicates an interface index of 2.  Or
    
    	fe80::215:c5ff:fe3b:e1b2%eth0
    
    indicates that requests should be routed through the eth0 device.
    Without the interface ID, link-local addresses are not usable for NFS.
    
    Both the kernel NFS client mount option parser and the mount.nfs command
    can take either form.  The mount.nfs command always passes the address
    through getnameinfo(3), which usually re-writes interface indices as
    device names.

    NFS: Support raw IPv6 address hostnames during NFS mount operation
    
    Traditionally the mount command has looked for a ":" to separate the
    server's hostname from the export path in the mounted on device name,
    like this:
    
    	mount server:/export /mounted/on/dir
    
    The server's hostname is "server" and the export path is "/export".
    
    You can also substitute a specific IPv4 network address for the server
    hostname, like this:
    
    	mount 192.168.0.55:/export /mounted/on/dir
    
    Raw IPv6 addresses present a problem, however, because they look
    something like this:
    
    	fe80::200:5aff:fe00:30b
    
    Note the use of colons.
    
    To get around the presence of colons, copy the Solaris convention used for
    mounting IPv6 servers by address: wrap a raw IPv6 address with square
    brackets.

    SUNRPC: Ensure all transports set rq_xtime consistently
    
    The RPC client uses the rq_xtime field in each RPC request to determine the
    round-trip time of the request.  Currently, the rq_xtime field is
    initialized by each transport just before it starts enqueing a request to
    be sent.  However, transports do not handle initializing this value
    consistently; sometimes they don't initialize it at all.
    
    To make the measurement of request round-trip time consistent for all
    RPC client transport capabilities, pull rq_xtime initialization into the
    RPC client's generic transport logic.  Now all transports will get a
    standardized RTT measure automatically, from:
    
      xprt_transmit()
    
    to
    
      xprt_complete_rqst()
    
    This makes round-trip time calculation more accurate for the TCP transport.
    The socket ->sendmsg() method can return "-EAGAIN" if the socket's output
    buffer is full, so the TCP transport's ->send_request() method may call
    the ->sendmsg() method repeatedly until it gets all of the request's bytes
    queued in the socket's buffer.
    
    Currently, the TCP transport sets the rq_xtime field every time through
    that loop so the final value is the timestamp just before the *last* call
    to the underlying socket's ->sendmsg() method.  After this patch, the
    rq_xtime field contains a timestamp that reflects the time just before the
    *first* call to ->sendmsg().
    
    This is consequential under heavy workloads because large requests often
    take multiple ->sendmsg() calls to get all the bytes of a request queued.
    The TCP transport causes the request to sleep until the remote end of the
    socket has received enough bytes to clear space in the socket's local
    output buffer.  This delay can be quite significant.
    
    The method introduced by this patch is a more accurate measure of RTT
    for stream transports, since the server can cause enough back pressure
    to delay (ie increase the latency of) requests from the client.
    
    Additionally, this patch corrects the behavior of the RDMA transport, which
    entirely neglected to initialize the rq_xtime field.  RPC performance
    metrics for RDMA transports now display correct RPC request round trip
    times.

    rpc: bring back cl_chatty
    
    The cl_chatty flag alows us to control whether a given rpc client leaves
    
    	"server X not responding, timed out"
    
    messages in the syslog.  Such messages make sense for ordinary nfs
    clients (where an unresponsive server means applications on the
    mountpoint are probably hanging), but not for the callback client (which
    can fail more commonly, with the only result just of disabling some
    optimizations).
    
    Previously cl_chatty was removed, do to lack of users; reinstate it, and
    use it for the nfsd's callback client.

    NFS: implement option checking when remounting NFS filesystems (resend)
    
    When remounting an NFS or NFS4 filesystem, the new NFS options are not
    respected, yet the remount will still return success. This patch adds
    a remount_fs sb op for NFS that checks any new nfs mount options against
    the existing ones and fails the mount if any have changed.
    
    This is only implemented for string-based mount options since doing
    this with binary options isn't really feasible.
    
    This is essentially the same as the original patch I sent out, but
    adds a check to see if the addr= option has changed.

    SUNRPC: Rename "call_" functions that are no longer FSM states
    
    The RPC client uses a finite state machine to move RPC tasks through each
    step of an RPC request.  Each state is contained in a function in
    net/sunrpc/clnt.c, and named call_foo.
    
    Some of the functions named call_foo have changed over the past few years and
    are no longer states in the FSM.  These include: call_encode, call_header,
    and call_verify.  As a clean up, rename the functions that have changed.

    NFS: Add correct bounds checking to NFSv2 locks
    
    NFSv2 file locking currently fails the Connectathon tests, because the
    calls to the VFS locking code do not return an EINVAL error if the
    struct file_lock overflows the 32-bit boundaries.
    
    The problem is due to the fact that we occasionally call helpers from
    fs/locks.c in order to avoid RPC calls to the server when we know that a
    local process holds the lock. These helpers are, of course, always
    64-bit enabled, so EINVAL is not returned in cases when it would if
    the call had gone to the NLM code.
    
    For consistency, we therefore add support for a bounds-checking helper.

    x86/pci: removing subsys_initcall ordering dependencies
    
    So far subsys_initcalls has been executed in this order depending on
    the object order in the Makefile:
    
    arch/x86/pci/visws.c:subsys_initcall(pcibios_init);
    arch/x86/pci/numa.c:subsys_initcall(pci_numa_init);
    arch/x86/pci/acpi.c:subsys_initcall(pci_acpi_init);
    arch/x86/pci/legacy.c:subsys_initcall(pci_legacy_init);
    arch/x86/pci/irq.c:subsys_initcall(pcibios_irq_init);
    arch/x86/pci/common.c:subsys_initcall(pcibios_init);
    
    This patch removes the ordering dependency. There is now only one
    subsys_initcall function that contains subsystem initialization code
    with a defined order.

    x86: fix C1E && nx6325 stability problem
    
    The problems are that, with the ACPI vs timer overring issue _fixed_,
    after using the box for some time (between several seconds and 1 hour, at
    random) processes get very high CPU loads (once I've got X using 107% of
    the CPU, for example) and the system becomes unresponsive, as though there
    were interrupts lost or something similar.
    
    Andreas Herrman reproduced similar problems:

    So lets fall back to the IRQ0/INT0 configuration on this box.
    
    This basically restores the dont-use-the-lapic-timer exception mechanism
    that was unconditional on this box prior commit 8750bf5 ("x86: add C1E
    aware idle function").

    x86: change asm constraint.
    
    Our integration efforts broke a build with this function being used
    with i386. Reason is "g" can put the operand in an imm32, which according
    to The Book (tm), is invalid as the second operand.
    
    This is actually a bug
    in x86_64 too, since the x86_64 instruction set reference does not list
    it as valid.
    
    We probably didn't trigger this before due to the ammount of
    registers available for 64-bit platforms. But that's just my guess.

    both versions does not need the word size specifiers, and we remove them.

    x86: explicitly use edx in const delay function.
    
    For x86_64, we can't just use %0, as it would

    powerpc/eeh: PERR/SERR bit settings during EEH device recovery
    
    The following patch restores the PERR and SERR bits in the PCI
    command register during an EEH device recovery. We have found
    at least one case (an Agilent test card) where the PERR/SERR
    bits are set to 1 by firmware at boot time, but are not restored
    to 1 during EEH recovery.  The patch fixes the Agilent card
    problem.  It has been tested on several other EEH-enabled cards
    with no regressions.

    compatibly on swapcontext.  swapcontext only compares the ucontext size
    passed in from the user to the new kernel ucontext size.
    
    This adds a check against the old ucontext size (with VMX but without
    VSX).  It also adds some sanity check for ucontexts without VSX, but
    where VSX is used according the MSR.  Fixes for both 32 and 64bit
    processes on 64bit kernels
    
    Kudos to Paulus for noticing.

    ibm_newemac: Parameterize EMAC Multicast Match Handling
    
    Various instances of the EMAC core have varying: 1) number of address
    match slots, 2) width of the registers for handling address match slots,
    3) number of registers for handling address match slots and 4) base
    offset for those registers.
    
    As the driver stands today, it assumes that all EMACs have 4 IAHT and
    GAHT 32-bit registers, starting at offset 0x30 from the register base,
    with only 16-bits of each used for a total of 64 match slots.
    
    The 405EX(r) and 460EX now use the EMAC4SYNC core rather than the EMAC4
    core. This core has 8 IAHT and GAHT registers, starting at offset 0x80
    from the register base, with ALL 32-bits of each used for a total of
    256 match slots.
    
    This adds a new compatible device tree entry "emac4sync" and a new,
    related feature flag "EMAC_FTR_EMAC4SYNC" along with a series of macros
    and inlines which supply the appropriate parameterized value based on
    the presence or absence of the EMAC4SYNC feature.
    
    The code has further been reworked where appropriate to use those macros
    and inlines.
    
    In addition, the register size passed to ioremap is now taken from the
    device tree:
    
    	c4 for EMAC4SYNC cores
    	74 for EMAC4 cores
    	70 for EMAC cores
    
    rather than sizeof (emac_regs).
    
    Finally, the device trees have been updated with the appropriate compatible
    entries and resource sizes.
    
    This has been tested on an AMCC Haleakala board such that: 1) inbound
    ICMP requests to 'haleakala.local' via MDNS from both Mac OS X 10.4.11
    and Ubuntu 8.04 systems as well as 2) outbound ICMP requests from
    'haleakala.local' to those same systems in the '.local' domain via MDNS
    now work.

    powerpc/mm: Don't clear _PAGE_COHERENT when _PAGE_SAO is set
    
    The current low level hash code on LPAR configurations clears
    _PAGE_COHERENT (M) when either _PAGE_GUARDED (G) or _PAGE_NO_CACHE (I)
    is set. This conflicts with _PAGE_SAO which has M, I and W bits sets at
    once (normally invalid combo) to indicate the new SAO attribute.
    
    This changes the code to allow that case.

    powerpc/mm: Add Strong Access Ordering support
    
    Allow an application to enable Strong Access Ordering on specific pages of
    memory on Power 7 hardware. Currently, power has a weaker memory model than
    x86. Implementing a stronger memory model allows an emulator to more
    efficiently translate x86 code into power code, resulting in faster code
    execution.
    
    On Power 7 hardware, storing 0b1110 in the WIMG bits of the hpte enables
    strong access ordering mode for the memory page.  This patchset allows a
    user to specify which pages are thus enabled by passing a new protection
    bit through mmap() and mprotect().  I have defined PROT_SAO to be 0x10.

    mm: Allow architectures to define additional protection bits
    
    This patch allows architectures to define functions to deal with
    additional protections bits for mmap() and mprotect().
    
    arch_calc_vm_prot_bits() maps additonal protection bits to vm_flags
    arch_vm_get_page_prot() maps additional vm_flags to the vma's vm_page_prot
    arch_validate_prot() checks for valid values of the protection bits
    
    Note: vm_get_page_prot() is now pretty ugly, but the generated code
    should be identical for architectures that don't define additional
    protection bits.

    iommu respect the segment size limits).
    
    This stops the function looking in the archdata.dma_data for the iommu
    table because in the future it will be called with a device that has
    no table there.
    
    This also has the nice side effect of making iommu_map_sg() match the

    x86: rename paravirtualized TSC functions
    
    Rename the paravirtualized calculate_cpu_khz to calibrate_tsc.
    In all cases, we actually calibrate_tsc and use that as the cpu_khz value.

    x86: merge tsc calibration
    
    Merge the tsc calibration code for the 32bit and 64bit kernel.
    The paravirtualized calculate_cpu_khz for 64bit now points to the correct
    tsc_calibrate code as in 32bit.
    Original native_calculate_cpu_khz for 64 bit is now called as calibrate_cpu.
    
    Also moved the recalibrate_cpu_khz function in the common file.
    Note that this function is called only from powernow K7 cpu freq driver.

    sysfs: add /sys/firmware/memmap
    
    This patch adds /sys/firmware/memmap interface that represents the BIOS
    (or Firmware) provided memory map. The tree looks like:
    
        /sys/firmware/memmap/0/start   (hex number)
                               end     (hex number)
                               type    (string)
        ...                 /1/start
                               end
                               type
    
    With the following shell snippet one can print the memory map in the same form
    the kernel prints itself when booting on x86 (the E820 map).
    
      --------- 8< --------------------------
        #!/bin/sh
        cd /sys/firmware/memmap
        for dir in * ; do
            start=$(cat $dir/start)
            end=$(cat $dir/end)
            type=$(cat $dir/type)
            printf "%016x-%016x (%s)\n" $start $[ $end +1] "$type"
        done
      --------- >8 --------------------------
    
    That patch only provides the needed interface:
    
     1. The sysfs interface.
     2. The structure and enumeration definition.
     3. The function firmware_map_add() and firmware_map_add_early()
        that should be called from architecture code (E820/EFI, for
        example) to add the contents to the interface.
    
    If the kernel is compiled without CONFIG_FIRMWARE_MEMMAP, the interface does
    nothing without cluttering the architecture-specific code with #ifdef's.
    
    The purpose of the new interface is kexec: While /proc/iomem represents
    the *used* memory map (e.g. modified via kernel parameters like 'memmap'
    and 'mem'), the /sys/firmware/memmap tree represents the unmodified memory
    map provided via the firmware. So kexec can:
    
     - use the original memory map for rebooting,
     - use the /proc/iomem for setting up the ELF core headers for kdump
       case that should only represent the memory of the system.
    
    The patch has been tested on i386 and x86_64.

    x86_32: remove __PAGE_KERNEL(_EXEC)
    From: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
    
    Older x86-32 processors do not support global mappings (PGD), so must
    only use it if the processor supports it.
    
    The _PAGE_KERNEL* flags always have _PAGE_KERNEL set, since logically
    we always want it set.
    
    This is OK even on processors which do not support PGD, since all
    _PAGE flags are masked with __supported_pte_mask before being turned
    into a real in-pagetable pte.  On 32-bit systems, __supported_pte_mask
    is initialized to not contain _PAGE_GLOBAL, and it is then added if
    the CPU is found to support it.
    
    The x86-32 code used to use __PAGE_KERNEL/__PAGE_KERNEL_EXEC for this
    purpose, but they're now redundant and can be removed.

    Consistently set _PAGE_GLOBAL in _PAGE_KERNEL flags.  This makes 32-

    __PAGE_KERNEL* did not have _PAGE_GLOBAL set, causing confusion as a
    result of the inconsistencies.
    
    This patch only affects x86-64, which generally always supports PGD.

    x86: move prefill_possible_map calling early
    
    call it right after we are done with MADT/mptable handling, instead of
    doing that in setup_per_cpu_areas() later on...
    
    this way for_possible_cpu() can be used early.

    x86: move init_cpu_to_node after get_smp_config
    
    when acpi=off, cpu_to_apicid is ready after get_smp_config
    so need to move init_cpu_to_node after it.
    
    otherwise, we will get wrong cpu->node mapping, and it will rely on
    amd_detect_cmp() to correct it - but that is too late as
    setup_per_cpu_data is already called before that so  we will get
    per_cpu_data on the wrong node.

    x86: find offset for crashkernel reservation automatically
    
    This patch removes the need of the crashkernel=...@offset parameter to define
    a fixed offset for crashkernel reservation. That feature can be used together
    with a relocatable kernel where the kexec-tools relocate the kernel and
    get the actual offset from /proc/iomem.
    
    The use case is a kernel where the .text+.data+.bss is after 16M physical
    memory (debug kernel with lockdep on x86_64 can cause that) which caused a
    major pain in autoconfiguration in our distribution.
    
    Also, that patch unifies crashdump architectures a bit since IA64 has
    that semantics from the very beginning of the kdump port.

    Phew.  OK, I've worked this out.  Short version is that's it's a false
    alarm, and there was no real failure here.  Long version:
    
        * I changed the code to create the physical mapping pagetables to
          reuse any existing mapping rather than replace it.   Specifically,
          reusing an pud pointed to by the pgd caused this symptom to appear.
        * The specific PUD being reused is the one created statically in
          head_64.S, which creates an initial 1GB mapping.
        * That mapping doesn't have _PAGE_GLOBAL set on it, due to the
          inconsistency between __PAGE_* and PAGE_*.
        * The CPA test attempts to clear _PAGE_GLOBAL, and then checks to
          see that the resulting range is 1) shattered into 4k pages, and 2)
          has no _PAGE_GLOBAL.
        * However, since it didn't have _PAGE_GLOBAL on that range to start
          with, change_page_attr_clear() had nothing to do, and didn't
          bother shattering the range,
        * resulting in the reported messages
    
    The simple fix is to set _PAGE_GLOBAL in level2_ident_pgt.
    
    An additional fix to make CPA testing more robust by using some other
    pagetable bit (one of the unused available-to-software ones).  This
    would solve spurious CPA test warnings under Xen which uses _PAGE_GLOBAL
    for its own purposes (ie, not under guest control).
    
    Also, we should revisit the use of _PAGE_GLOBAL in asm-x86/pgtable.h,
    and use it consistently, and drop MAKE_GLOBAL.  The first time I
    proposed it it caused breakages in the very early CPA code; with luck
    that's all fixed now.

    x86: move reserve_setup_data to setup.c
    
    Ying Huang would like setup_data to be reserved, but not included in the
    no save range.
    
    Here we try to modify the e820 table to reserve that range early.
    also add that in early_res in case bootloader messes up with the ramdisk.
    
    other solution would be
    1. add early_res_to_highmem...
    2. early_res_to_e820...
    but they could reserve another type memory wrongly, if early_res has some
    resource reserved early, and not needed later, but it is not removed from
    early_res in time. Like the RAMDISK (already handled).

    I don't know if this will fix this bug, but it's definitely a bugfix.
    It was trashing random pages by overwriting them with pagetables...
    
    Don't trash a large pmd's data when mapping physical memory.
    This is a bugfix for "x86_64: adjust mapping of physical pagetables
    to work with Xen".

    x86: limit E820 map when a user-defined memory map is specified
    
    This patch brings back limiting of the E820 map when a user-defined
    E820 map is specified. While the behaviour of i386 (32 bit) was to limit
    the E820 map (and /proc/iomem), the behaviour of x86-64 (64 bit) was not to
    limit.
    
    That patch limits the E820 map again for both x86 architectures.
    
    Code was tested for compilation and booting on a 32 bit and 64 bit system.

    sysexit - just return to userspace, does no register restoration of
        any kind; must explicitly atomically enable interrupts.
    
    sysret - reloads flags from r11, so no need to explicitly enable
        interrupts on 64-bit, responsible for restoring usermode %gs

    x86: use __KERNEL_DS as SS when returning to a kernel thread
    
    This is needed when the kernel is running on RING3, such as under Xen.
    x86_64 has a weird feature that makes it #GP on iret when SS is a null

    This need to be tested on bare metal to make sure it doesn't cause any

    x86, 64-bit: adjust mapping of physical pagetables to work with Xen
    
    This makes a few of changes to the construction of the initial
    pagetables to work better with paravirt_ops/Xen.  The main areas
    are:
    
     1. Support non-PSE mapping of memory, since Xen doesn't currently
        allow 2M pages to be mapped in guests.
    
     2. Make sure that the ioremap alias of all pages are dropped before
        attaching the new page to the pagetable.  This avoids having
        writable aliases of pagetable pages.
    
     3. Preserve existing pagetable entries, rather than overwriting.  Its
        possible that a fair amount of pagetable has already been constructed,
        so reuse what's already in place rather than ignoring and overwriting it.
    
    The algorithm relies on the invariant that any page which is part of
    the kernel pagetable is itself mapped in the linear memory area.  This
    way, it can avoid using ioremap on a pagetable page.
    
    The invariant holds because it maps memory from low to high addresses,
    and also allocates memory from low to high.  Each allocated page can
    map at least 2M of address space, so the mapped area will always
    progress much faster than the allocated area.  It relies on the early
    boot code mapping enough pages to get started.

    x86, 64-bit: split x86_64_start_kernel
    
    Split x86_64_start_kernel() into two pieces:
    
       The first essentially cleans up after head_64.S.  It clears the
       bss, zaps low identity mappings, sets up some early exception
       handlers.
    
       The second part preserves the boot data, reserves the kernel's
       text/data/bss, pagetables and ramdisk, and then starts the kernel
       proper.
    
    This split is so that Xen can call the second part to do the set up it
    needs done.  It doesn't need any of the first part setups, because it
    doesn't boot via head_64.S, and its redundant or actively damaging.

    Set __PAGE_OFFSET to the most negative possible address +

    The gap is more or less arbitrary, but it's what Xen needs.

    x86/paravirt: define PARA_INDIRECT for indirect asm calls
    
    On 32-bit it's best to use a %cs: prefix to access memory where the
    other segments may not bet set up properly yet.  On 64-bit it's best
    to use a rip-relative addressing mode.  Define PARA_INDIRECT() to
    abstract this and generate the proper addressing mode in each case.

    x86: preallocate and prepopulate separately
    
    Jan Beulich points out that vmalloc_sync_all() assumes that the
    kernel's pmd is always expected to be present in the pgd.  The current
    pgd construction code will add the pgd to the pgd_list before its pmds
    have been pre-populated, thereby making it visible to
    vmalloc_sync_all().
    
    However, because pgd_prepopulate_pmd also does the allocation, it may
    block and cannot be done under spinlock.
    
    The solution is to preallocate the pmds out of the spinlock, then
    populate them while holding the pgd_list lock.
    
    This patch also pulls the pmd preallocation and mop-up functions out
    to be common, assuming that the compiler will generate no code for
    them when PREALLOCTED_PMDS is 0.  Also, there's no need for pgd_ctor
    to clear the pgd again, since it's allocated as a zeroed page.

    x86: simplify vmalloc_sync_all
    
    vmalloc_sync_all() is only called from register_die_notifier and
    alloc_vm_area.  Neither is on any performance-critical paths, so
    vmalloc_sync_all() itself is not on any hot paths.
    
    Given that the optimisations in vmalloc_sync_all add a fair amount of
    code and complexity, and are fairly hard to evaluate for correctness,
    it's better to just remove them to simplify the code rather than worry
    about its absolute performance.

    x86 boot: only pick up additional EFI memmap if add_efi_memmap flag
    
    Applies on top of the previous patch:
      x86 boot: add code to add BIOS provided EFI memory entries to kernel
    
    Instead of always adding EFI memory map entries (if present) to the
    memory map after initially finding either E820 BIOS memory map entries
    and/or kernel command line memmap entries, -instead- only add such
    additional EFI memory map entries if the kernel boot option:
    
        add_efi_memmap
    
    is specified.
    
    Requiring this 'add_efi_memmap' option is backward compatible with
    kernels that didn't load such additional EFI memory map entries in
    the first place, and it doesn't override a configuration that tries
    to replace all E820 or EFI BIOS memory map entries with ones given
    entirely on the kernel command line.

    mm, generic, x86 boot: more tweaks to hex prints of some pfn addresses
    
    Fix some problems with (and applies on top of) a previous patch:
      x86 boot: show pfn addresses in hex not decimal in some kernel info printks
    
    Primarily change "0x%8lx" format, which displays with a right aligned
    space filled hex number (spaces between the "0x" prefix and the number),
    into "%0#10lx" format, which zero fills instead of space fills, and
    which uses the printf flag '#' to request the "0x" prefix instead of
    hard coding it.
    
    Also replace some other "0x%lx" formats with "%#lx", making use of the
    '#' printf flag again.

    that range is from find_e820_area, so don't try to use end_pfn to see
    if out of boundary...use table_top instead to avoid possible strange
    result while cross the boundary...
    
    also change early_printk to printk, because init_memory_mapping is after
    early param parsing, and console=uart8250 already working at that time.

    x86: nmi_watchdog - use NMI_NONE by default
    
    There is no need to keep NMI_DISABLED definition and use it
    for nmi_watchdog by default. Here is the point why:
    
    - IO-APIC and APIC chips are programmed for nmi_watchdog support at very
      early stage of kernel booting and not having nmi_watchdog specified as
      boot option lead only to nmi_watchdog becomes to NMI_NONE anyway
    - enable nmi_watchdog thru /proc/sys/kernel/nmi if it was not specified at
      boot is not possible too (even having this sysfs entry)

    x86 boot: allow overlapping early reserve memory ranges
    
    Add support for overlapping early memory reservations.
    
    In general, they still can't overlap, and will panic
    with "Overlapping early reservations" if they do overlap.
    
    But if a memory range is reserved with the new call:
        reserve_early_overlap_ok()
    rather than with the usual call:
        reserve_early()
    then subsequent early reservations are allowed to overlap.
    
    This new reserve_early_overlap_ok() call is only used in one
    place so far, which is the "BIOS reserved" reservation for the
    the EBDA region, which out of Paranoia reserves more than what
    the BIOS might have specified, and which thus might overlap with
    another legitimate early memory reservation (such as, perhaps,
    the EFI memmap.)

    x86: take load_sp0 out of smpboot.c
    
    there's no particular reason to do load_sp0 in different
    places for i386 and x86_64. They should all be in cpu_init.
    Right now, cpu_init itself is not integrated, but with this patch,
    the code becomes closer to each other, making in easier to integrate
    when the time comes.
    
    Furthermore, although doing it in do_boot_cpu for x86_64 is fine, since it's
    only a copy, load_sp0 should be executed in the cpu it refers to anyway.

    build: add __page_aligned_data and __page_aligned_bss
    
    Making a variable page-aligned by using
    __attribute__((section(".data.page_aligned"))) is fragile because if
    sizeof(variable) is not also a multiple of page size, it leaves
    variables in the remainder of the section unaligned.
    
    This patch introduces two new qualifiers, __page_aligned_data and
    __page_aligned_bss to set the section *and* the alignment of
    variables.  This makes page-aligned variables more robust because the
    linker will make sure they're aligned properly.  Unfortunately it
    requires *all* page-aligned data to use these macros...

    x86: unify crashkernel reservation for 32 and 64 bit
    
    This patch moves the reserve_crashkernel() to setup.c and removes the
    architecture-specific version. Both versions were more or less the same.
    
    I tested it on both x86-64 and i386, with CONFIG_KEXEC on and off (so
    that it compiles).

    physid_mask_of_physid() causes a huge stack (12k) to be created if the

    x86, SGI UV: TLB shootdown using broadcast assist unit
    
    TLB shootdown for SGI UV.
    
    Depends on patch (in tip/x86/irq):
       x86-update-macros-used-by-uv-platform.patch   Jack Steiner May 29
    
    This patch provides the ability to flush TLB's in cpu's that are not on
    the local node.  The hardware mechanism for distributing the flush
    messages is the UV's "broadcast assist unit".
    
    The hook to intercept TLB shootdown requests is a 2-line change to
    native_flush_tlb_others() (arch/x86/kernel/tlb_64.c).
    
    This code has been tested on a hardware simulator. The real hardware
    is not yet available.
    
    The shootdown statistics are provided through /proc/sgi_uv/ptc_statistics.
    The use of /sys was considered, but would have required the use of
    many /sys files.  The debugfs was also considered, but these statistics
    should be available on an ongoing basis, not just for debugging.
    
    Issues to be fixed later:
    - The IRQ for the messaging interrupt is currently hardcoded as 200
      (see UV_BAU_MESSAGE).  It should be dynamically assigned in the future.
    - The use of appropriate udelay()'s is untested, as they are a problem
      in the simulator.

    x86: use reserve_bootmem_generic() to reserve crashkernel memory on x86_64
    
    This patch uses reserve_bootmem_generic() instead of reserve_bootmem()
    to reserve the crashkernel memory on x86_64. That's necessary for NUMA
    machines, see 00212fef814612245ed0261cbac8426d0c9a31a5:
    
      [PATCH] Fix kdump Crash Kernel boot memory reservation for NUMA machines
    
      This patch will fix a boot memory reservation bug that trashes memory on
      the ES7000 when loading the kdump crash kernel.
    
      The code in arch/x86_64/kernel/setup.c to reserve boot memory for the crash
      kernel uses the non-numa aware "reserve_bootmem" function instead of the
      NUMA aware "reserve_bootmem_generic".  I checked to make sure that no other
      function was using "reserve_bootmem" and found none, except the ones that
      had NUMA ifdef'ed out.
    
      I have tested this patch only on an ES7000 with NUMA on and off (numa=off)
      in a single (non-NUMA) and multi-cell (NUMA) configurations.

    x86: add flags parameter to reserve_bootmem_generic()
    
    This patch adds a 'flags' parameter to reserve_bootmem_generic() like it
    already has been added in reserve_bootmem() with commit
    72a7fe3967dbf86cb34e24fbf1d957fe24d2f246.
    
    It also changes all users to use BOOTMEM_DEFAULT, which doesn't effectively
    change the behaviour. Since the change is x86-specific, I don't think it's
    necessary to add a new API for migration. There are only 4 users of that
    function.
    
    The change is necessary for the next patch, using reserve_bootmem_generic()
    for crashkernel reservation.

    x86: remove static boot_cpu_pda array v2
    
      * Remove the boot_cpu_pda array and pointer table from the data section.
        Allocate the pointer table and array during init.  do_boot_cpu()
        will reallocate the pda in node local memory and if the cpu is being
        brought up before the bootmem array is released (after_bootmem = 0),
        then it will free the initial pda.  This will happen for all cpus
        present at system startup.
    
        This removes 512k + 32k bytes from the data section.
    
    For inclusion into sched-devel/latest tree.

      * Consolidate node_to_cpumask operations and remove the 256k
        byte node_to_cpumask_map.  This is done by allocating the
        node_to_cpumask_map array after the number of possible nodes

      * Restore the nodenumber field in the x86_64 pda.  This field is slightly

    x86: cleanup early per cpu variables/accesses v4
    
      * Introduce a new PER_CPU macro called "EARLY_PER_CPU".  This is
        used by some per_cpu variables that are initialized and accessed
        before there are per_cpu areas allocated.
    
        ["Early" in respect to per_cpu variables is "earlier than the per_cpu
        areas have been setup".]
    
        This patchset adds these new macros:
    
    	DEFINE_EARLY_PER_CPU(_type, _name, _initvalue)
    	EXPORT_EARLY_PER_CPU_SYMBOL(_name)
    	DECLARE_EARLY_PER_CPU(_type, _name)
    
    	early_per_cpu_ptr(_name)
    	early_per_cpu_map(_name, _idx)
    	early_per_cpu(_name, _cpu)
    
        The DEFINE macro defines the per_cpu variable as well as the early
        map and pointer.  It also initializes the per_cpu variable and map
        elements to "_initvalue".  The early_* macros provide access to
        the initial map (usually setup during system init) and the early
        pointer.  This pointer is initialized to point to the early map
        but is then NULL'ed when the actual per_cpu areas are setup.  After
        that the per_cpu variable is the correct access to the variable.
    
        The early_per_cpu() macro is not very efficient but does show how to
        access the variable if you have a function that can be called both
        "early" and "late".  It tests the early ptr to be NULL, and if not
        then it's still valid.  Otherwise, the per_cpu variable is used
        instead:
    
    	#define early_per_cpu(_name, _cpu) 			\
    		(early_per_cpu_ptr(_name) ?			\
    			early_per_cpu_ptr(_name)[_cpu] :	\
    			per_cpu(_name, _cpu))
    
        A better method is to actually check the pointer manually.  In the
        case below, numa_set_node can be called both "early" and "late":
    
    	void __cpuinit numa_set_node(int cpu, int node)
    	{
    	    int *cpu_to_node_map = early_per_cpu_ptr(x86_cpu_to_node_map);
    
    	    if (cpu_to_node_map)
    		    cpu_to_node_map[cpu] = node;
    	    else
    		    per_cpu(x86_cpu_to_node_map, cpu) = node;
    	}
    
      * Add a flag "arch_provides_topology_pointers" that indicates pointers
        to topology cpumask_t maps are available.  Otherwise, use the function
        returning the cpumask_t value.  This is useful if cpumask_t set size
        is very large to avoid copying data on to/off of the stack.
    
      * The coverage of CONFIG_DEBUG_PER_CPU_MAPS has been increased while
        the non-debug case has been optimized a bit.
    
      * Remove an unreferenced compiler warning in drivers/base/topology.c
    
      * Clean up #ifdef in setup.c

    Ok, I think I found it.  In check_nmi_watchdog():
    
            for (cpu = 0; cpu < NR_CPUS; cpu++)
                    prev_nmi_count[cpu] = cpu_pda(cpu)->__nmi_count;
    
    As I mentioned it works fine on both of my systems so could you try it out?
    
    Thanks!

    x86, ioapic, acpi quirk: disable IRQ 0 through I/O APIC for some HP systems
    
    Some HP laptops have a problem with their DSDT reporting as
    HP/SB400/10000, which includes some code which overrides all temperature
    trip points to 16C if the INTIN2 input of the I/O APIC is enabled.  This
    input is incorrectly designated the ISA IRQ 0 via an interrupt source
    override even though it is wired to the output of the master 8259A and
    INTIN0 is not connected at all.  So far two models have been identified,
    namely nx6125 and nx6325.
    
    Use a knob provided by the I/O APIC interrupt registration code to
    abandon any attempts to route IRQ 0 through the I/O APIC for these
    systems.

    x86, ioapic, acpi: add a knob to disable IRQ 0 through I/O APIC
    
    As discovered recently some systems exhibit problems when the 8254 timer
    IRQ is routed through the I/O APIC.  These problems do not affect the
    timer IRQ itself and therefore cannot be detected when the correctness of
    operation of the interrupt is verified in check_timer().  Therefore the
    I/O APIC path of the timer IRQ has to be disabled entirely.
    
    This is a change that lets platforms ask for the timer IRQ not to be
    registered in the I/O APIC interrupt tables.  The local APIC and ExtINTA
    paths are unaffected.  This request is only taken into account for ACPI
    platforms as MP table systems seem unaffected so far.

    x86 boot: pass E820 memory map entries more than 128 via linked list of setup data
    
    Because of the size limits of struct boot_params (zero page), the
    maximum number of E820 memory map entries can be passed to kernel is
    128. As pointed by Paul Jackson, there is some machine produced by SGI
    with so many nodes that the number of E820 memory map entries is more
    than 128. To enabling Linux kernel on these system, a new setup data
    type named SETUP_E820_EXT is defined to pass additional memory map
    entries to Linux kernel.
    
    This patch is based on x86/auto-latest branch of git-x86 tree and has
    been tested on x86_64 and i386 platform.

    x86: use reserve_bootmem_generic() to reserve crashkernel memory on x86_64
    
    This patch uses reserve_bootmem_generic() instead of reserve_bootmem()
    to reserve the crashkernel memory on x86_64. That's necessary for NUMA
    machines, see 00212fef814612245ed0261cbac8426d0c9a31a5:
    
      [PATCH] Fix kdump Crash Kernel boot memory reservation for NUMA machines
    
      This patch will fix a boot memory reservation bug that trashes memory on
      the ES7000 when loading the kdump crash kernel.
    
      The code in arch/x86_64/kernel/setup.c to reserve boot memory for the crash
      kernel uses the non-numa aware "reserve_bootmem" function instead of the
      NUMA aware "reserve_bootmem_generic".  I checked to make sure that no other
      function was using "reserve_bootmem" and found none, except the ones that
      had NUMA ifdef'ed out.
    
      I have tested this patch only on an ES7000 with NUMA on and off (numa=off)
      in a single (non-NUMA) and multi-cell (NUMA) configurations.

    x86: add flags parameter to reserve_bootmem_generic()
    
    This patch adds a 'flags' parameter to reserve_bootmem_generic() like it
    already has been added in reserve_bootmem() with commit
    72a7fe3967dbf86cb34e24fbf1d957fe24d2f246.
    
    It also changes all users to use BOOTMEM_DEFAULT, which doesn't effectively
    change the behaviour. Since the change is x86-specific, I don't think it's
    necessary to add a new API for migration. There are only 4 users of that
    function.
    
    The change is necessary for the next patch, using reserve_bootmem_generic()
    for crashkernel reservation.

     Hmm, that only proved the 8259A is indeed wired to the pin #2 of the I/O
    APIC.

     Well, the IC block is most likely the same as that's not rocket science
    and once done there is no need to fiddle with that.  That written, I am
    afraid there is nothing useful about the IC in the document, except that
    it's there and consists of an I/O APIC providing 24 inputs and the usual
    pair of 8259A cores.  Thanks for the reference anyway.
    
    > There is an interrupt controller in there, but I'm not sure if there's any
    > 8259A.  The northbridge is on the CPU, actually.
    
     I will praise the day someone ships an x86 machine without an 8259A core!
    
     As expressed in another mail I suspect there may actually be a direct
    route from the 8254 to INTIN0 in the southbridge -- this is what other
    bootstrap logs seen in the Internet suggest.  This would mean this
    particular BIOS is buggy (is it the latest version?) and provides an
    incorrect IRQ override in its ACPI tables, for example because the
    responsible block has been blindly copied from a machine using a commoner
    wiring.  This could be moderately easily fixed up with a quirk based on
    the PCI ID (after checking it again, we actually used to have a quirk for
    ATI in this area, but the way it was done suggests the issue was not
    understood well enough).
    
     Could you please remove the hack sent yesterday and test the patch
    provided below?  I do hope it builds, but I have no immediate means to
    check it.  Please report the output.  The intent is to test INTIN0
    directly before testing INTIN2 through the 8259A.  Thanks.
    
     Aside of that, what I have gathered from your reports (please correct me
    if I have got it wrong) is that when the through-8259A mode is used, then
    after a while 8254 timer interrupts stop arriving.  What's interesting,
    the "Virtual Wire IRQ" seems to work for you correctly (that's quite an
    odd setup where a local APIC input is used in the native mode -- please
    post /proc/interrupts for confirmation), which in turn implies the master
    8259A drives its INT output as we expect.  Why would the I/O APIC input
    have problems then?  Hmm...

    Thanks.  In this case I suspect the case #1 quoted above happens, that is
    the 8259A manages to deliver its interrupt somehow.  Note at this stage it
    is meant to be in the AEOI mode, so it can happily resubmit the interrupt
    indefinitely with no additional handling as long as it receives INTA
    cycles.
    
    Can you please try the patch below on top of "x86: I/O APIC: timer
    through 8259A second-chance" to see whether my hypothesis is true?  It
    modifies the through-8259A setup path so that the APIC input gets masked,
    but the 8259A has the timer interrupt still enabled.  Let me know how the
    timer interrupt is routed in this case.

    x86: APIC/UP: Downgrade the NMI watchdog for no I/O APIC
    
     If configured to use the I/O APIC, the NMI watchdog is deemed to fail if
    the chip will not be used in the UP configuration, because "noapic" has
    been specified or the chip is simply not there.  Downgrade to the local
    APIC watchdog to rectify.
    
    The new #ifdef is ugly, I know.  A proper solution is to provide suitable
    definitions of smp_found_config, etc. for !CONFIG_X86_IO_APIC in a header.
    Likewise the whole if () condition should be moved to a static inline
    function.  Such clean-ups are beyond the scope of this change and can be
    done once the whole issue of the timer has been sorted out.

    x86: I/O APIC: timer through 8259A second-chance
    
    Some systems incorrectly report the ExtINTA pin of the I/O APIC as the
    genuine target of the timer interrupt.  Here is a change that copies timer
    pin information found to the other pin if one has been found only.  This
    way both a direct and a through-8259A route is tested with the pin letting
    these problematic systems work well enough.  If no timer pin information
    has been found for the I/O APIC, then local APIC variations are tried
    only, similarly to what is done without the change (except without the
    misleading messages).
    
    Obviously if we try the first-chance path without being told by the BIOS
    to do so, we should not complain either, so do not print the message in
    this case.
    
    The 64-bit variation should be updated with a call to
    replace_pin_at_irq() which can be done with the upcoming merge.  Since
    add_pin_to_irq() is now always called in the first-chance path, the
    condition to require it in the second-chance path no longer happens.

    x86: I/O APIC: remove parameters to fiddle with the 8259A
    
    Remove the "disable_8254_timer" and "enable_8254_timer" kernel
    parameters.  Now that AEOI acknowledgements are no longer needed for
    correct timer operation, the 8259A can be kept disabled unconditionally
    unless interrupts, either timer or watchdog ones, are actually passed
    through it.

    x86: I/O APIC: AEOI timer acknowledgement clean-ups
    
    The code that used to be in do_slow_gettimeoffset() that relied on the
    IRR bit of the master 8259A PIC for IRQ0 to check the state of the output
    timer 0 of the PIT is no longer there.  As a result, there is no need to
    use the POLL command to acknowledge the timer interrupt in the "8259A
    Virtual Wire", except for the NMI watchdog when the i82489DX APIC is used
    (this is because this particular APIC treats NMIs as level-triggered and
    keeping the input asserted would keep motherboard NMI sources held off for
    too long).  Remove the unneeded bits and adjust comments accordingly.

    x86, generic: CPA add statistics about state of direct mapping v4
    
    Add information about the mapping state of the direct mapping to
    /proc/meminfo. I chose /proc/meminfo because that is where all the other
    memory statistics are too and it is a generally useful metric even
    outside debugging situations. A lot of split kernel pages means the
    kernel will run slower.
    
    This way we can see how many large pages are really used for it and how
    many are split.
    
    Useful for general insight into the kernel.

    The BROADCAST_FORCE notification uses smp_function_call and therefor
    must be run with interrupts enabled.

    x86, clockevents: add C1E aware idle function
    
    C1E on AMD machines is like C3 but without control from the OS. Up to
    now we disabled the local apic timer for those machines as it stops
    when the CPU goes into C1E. This excludes those machines from high
    resolution timers / dynamic ticks, which hurts especially X2 based
    laptops.
    
    The current boot time C1E detection has another, more serious flaw
    as well: some BIOSes do not enable C1E until the ACPI processor module
    is loaded. This causes systems to stop working after that point.
    
    To work nicely with C1E enabled machines we use a separate idle
    function, which checks on idle entry whether C1E was enabled in the
    Interrupt Pending Message MSR. This allows us to do timer broadcasting
    for C1E and covers the late enablement of C1E as well.

    PCI ACPI: Rework PCI handling of wake-up

      disabling the system wake-up capability of devices that are power
      manageable by ACPI.
    
    * Introduce function acpi_bus_can_wakeup() allowing other (dependent)
      subsystems to check if ACPI is able to enable the system wake-up
      capability of given device.
    
    * Introduce callback .sleep_wake() in struct pci_platform_pm_ops and
      for the ACPI PCI 'driver' make it use acpi_pm_device_sleep_wake().
    
    * Introduce callback .can_wakeup() in struct pci_platform_pm_ops and
      for the ACPI 'driver' make it use acpi_bus_can_wakeup().
    
    * Move the PME# handlig code out of pci_enable_wake() and split it
      into two functions, pci_pme_capable() and pci_pme_active(),
      allowing the caller to check if given device is capable of
      generating PME# from given power state and to enable/disable the
      device's PME# functionality, respectively.
    
    * Modify pci_enable_wake() to use the new ACPI callbacks and the new
      PME#-related functions.
    
    * Drop the generic .platform_enable_wakeup() callback that is not
      used any more.
    
    * Introduce device_set_wakeup_capable() that will set the
      power.can_wakeup flag of given device.
    
    * Rework PCI device PM initialization so that, if given device is
      capable of generating wake-up events, either natively through the
      PME# mechanism, or with the help of the platform, its
      power.can_wakeup flag is set and its power.should_wakeup flag is
      unset as appropriate.
    
    * Make ACPI set the power.can_wakeup flag for devices found to be
      wake-up capable by it.
    
    * Make the ACPI wake-up code enable/disable GPEs for devices that
      have the wakeup.flags.prepared flag set (which means that their
      wake-up power has been enabled).

    [GFS2] Allow local DF locks when holding a cached EX glock
    
    We already allow local SH locks while we hold a cached EX glock, so here
    we allow DF locks as well. This works only because we rely on the VFS's
    invalidation for locally cached data, and because if we hold an EX lock,
    then we know that no other node can be caching data relating to this
    file.
    
    It dramatically speeds up initial writes to O_DIRECT files since we fall
    back to buffered I/O for this and would otherwise bounce between DF and
    EX modes on each and every write call. The lessons to be learned from
    that are to ensure that (for the time being anyway) O_DIRECT files are
    preallocated and that they are written to using reasonably large I/O
    sizes. Even so this change fixes that corner case nicely

    Internal clock path handling for the i.MX27 CPU.
    
    Changed against the original Freescale code (and against clocklib for example):
     - clock rate is always calculated whenever one ask for the current rate.
       (means no "rate" member in the clock structure).
       So switching the PLL base frequency will propagate immediately to all
       other clocks that are depending on this frequency.

    i.MX3: Add a basic default config for the imx31ads (reference only)
    
    Currently there is a mx31ads BSP file in the kernel, but no default
    config file.
    
    This patch adds a basic default config for the imx31ads but it is for test
    purposes only to ensure the i.MX2 patch stack doesn't break the i.MX3.
    
    Note: For reference only. This configuration is untested as I have
    no access to an mx31ads.

    i.MXC family: Adding timer support
    
    This patch adds timer support for the i.MX machine family. This code can
    be used on the following machs:
    
     - i.MX1 (tested)
     - i.MX2 (i.MX21 (to be tested), i.MX27 (tested))
     - i.MX3 (i.MX31 (tested))
    
    TODO: It seems impossible to build a kernel for more than one CPU because the
    timer do not follow the platform device rules. So it does only work if
    timer 1 can be accessed on all CPUs at the same address.

    MXC family: Add clock handling
    
    Internal clock path handling for the mxc CPUs.
    
    Changed against the original Freescale code (and against clocklib for example):
     - clock rate is always calculated whenever one ask for the current rate
       (means struct clk has no more a member called "rate"). So switching the PLL
       base frequency will propagate immediately to all other clocks that are
       depending on this frequency.

    sched: add avg-overlap support to RT tasks
    
    We have the notion of tracking process-coupling (a.k.a. buddy-wake) via
    the p->se.last_wake / p->se.avg_overlap facilities, but it is only used
    for cfs to cfs interactions.  There is no reason why an rt to cfs
    interaction cannot share in establishing a relationhip in a similar
    manner.
    
    Because PREEMPT_RT runs many kernel threads as FIFO priority, we often
    times have heavy interaction between RT threads waking CFS applications.
    This patch offers a substantial boost (50-60%+) in perfomance under those
    circumstances.

    splice: fix generic_file_splice_read() race with page invalidation
    
    If a page was invalidated during splicing from file to a pipe, then
    generic_file_splice_read() could return a short or zero count.
    
    This manifested itself in rare I/O errors seen on nfs exported fuse
    filesystems.  This is because nfsd uses splice_direct_to_actor() to read
    files, and fuse uses invalidate_inode_pages2() to invalidate stale data on
    open.
    
    Fix by redoing the page find/create if it was found to be truncated
    (invalidated).

    kmalloced buffers for packet commands to avoid stack corruption on non
    coherent platforms.
    
    SCSI cdrom uses blk_rq_map_kern, which properly avoids DMA on the
    stack by using the bounce buffers. IDE cdrom also has the mechnism to
    avoids DMA on the stack. So we don't need this extra complexitiy in
    cdrom.c, such as allocating just 8 bytes. The lower layers can handle
    it.

    scsi: sr avoids useless buffer allocation
    
    blk_rq_map_kern can handle the stack buffers correctly (avoid DMA
    from/to the stack buffers by using the bounce buffer) so we don't need
    to complicate the code by allocating just 8 bytes.

    block: blk_rq_map_kern uses the bounce buffers for stack buffers
    
    blk_rq_map_kern is used for kernel internal I/Os. Some callers use
    this function with stack buffers but DMA to/from the stack buffers
    leads to memory corruption on a non-coherent platform.
    
    This patch make blk_rq_map_kern uses the bounce buffers if a caller
    passes a stack buffer (on the all platforms for simplicity).

    block: add blk_queue_update_dma_pad
    
    This adds blk_queue_update_dma_pad to prevent LLDs from overwriting
    the dma pad mask wrongly (we added blk_queue_update_dma_alignment due
    to the same reason).
    
    This also converts libata to use blk_queue_update_dma_pad instead of
    blk_queue_dma_pad.

    [ARM] 5087/1: Get the PWM layer to handle clock enable/disable properly.
    
    Allow pwm_enable()/pwm_disable() to be called as many times
    as the driver wants (and not even count them).
    The PWM model is different from things like the clock API
    where we need enable counting, because PWMs have one
    exclusive user per PWM whereas the clock API can have
    multiple users of the same clock.

    Add bvec_merge_data to handle stacked devices and ->merge_bvec()
    
    When devices are stacked, one device's merge_bvec_fn may need to perform
    the mapping and then call one or more functions for its underlying devices.
    
    The following bio fields are used:
      bio->bi_sector
      bio->bi_bdev
      bio->bi_size
      bio->bi_rw  using bio_data_dir()
    
    This patch creates a new struct bvec_merge_data holding a copy of those
    fields to avoid having to change them directly in the struct bio when
    going down the stack only to have to change them back again on the way
    back up.  (And then when the bio gets mapped for real, the whole
    exercise gets repeated, but that's a problem for another day...)

    xen: Avoid allocations causing swap activity on the resume path
    
    Avoid allocations causing swap activity on the resume path by
    preventing the allocations from doing IO and allowing them
    to access the emergency pools.
    
    These paths are used when a frontend device is trying to connect
    to its backend driver over Xenbus.  These reconnections are triggered
    on demand by IO, so by definition there is already IO underway,
    and further IO would naturally deadlock.  On resume, this path
    is triggered when the running system tries to continue using its
    devices.  If it cannot then the resume will fail; to try to avoid this
    we let it dip into the emergency pools.

    ARM: OMAP2: Clock: New OMAP2/3 DPLL rate rounding algorithm
    
    This patch adds a new rate rounding algorithm for DPLL clocks on the
    OMAP2/3 architecture.
    
    For a desired DPLL target rate, there may be several
    multiplier/divider (M, N) values which will generate a sufficiently
    close rate.  Lower N values result in greater power economy.  However,
    lower N values can cause the difference between the rounded rate and
    the target rate ("rate error") to be larger than it would be with a
    higher N.  This can cause downstream devices to run more slowly than
    they otherwise would.
    
    This DPLL rate rounding algorithm:
    
    - attempts to find the lowest possible N (DPLL divider) to reach the
      target_rate (since, according to Richard Woodruff <r-woodruff@ti.com>,
      lower N values save more power than higher N values).
    
    - allows developers to set an upper bound on the error between the
      rounded rate and the desired target rate ("rate tolerance"), so an
      appropriate balance between rate fidelity and power savings can be
      set.  This maximum rate error tolerance is set via
      omap2_set_dpll_rate_tolerance().
    
    - never returns a rounded rate higher than the target rate.
    
    The rate rounding algorithm caches the last rounded M, N, and rate
    computation to avoid rounding the rate twice for each clk_set_rate()
    call.  (This patch does not yet implement set_rate for DPLLs; that
    follows in a future patch.)
    
    The algorithm trades execution speed for rate accuracy.  It will find
    the (M, N) set that results in the least rate error, within a
    specified rate tolerance.  It does this by evaluating each divider
    setting - on OMAP3, this involves 128 steps.  Another approach to DPLL
    rate rounding would be to bail out as soon as a valid rate is found
    within the rate tolerance, which would trade rate accuracy for
    execution speed.  Alternate implementations welcome.
    
    This code is not yet used by the OMAP24XX DPLL clock, since it
    is currently defined as a composite clock, fusing the DPLL M,N and the
    M2 output divider.  This patch also renames the existing OMAP24xx DPLL
    programming functions to highlight that they program both the DPLL and
    the DPLL's output multiplier.

    ARM: OMAP2: Clock: Add OMAP3 DPLL autoidle functions
    
    This patch adds support for DPLL autoidle control to the OMAP3 clock
    framework.  These functions will be used by the noncore DPLL enable
    and disable code - this is because, according to the CDP code, the
    DPLL autoidle status must be saved and restored across DPLL
    lock/bypass/off transitions.
    
    N.B.: the CORE DPLL (DPLL3) has three autoidle mode options, rather
    than just two.  This code currently does not support the third option,
    low-power bypass autoidle.

    ARM: OMAP: Add OMAP chip type structure; clean up mach-omap2/id.c
    
    Add a new OMAP chip identification interface, omap_chip_id.
    omap_chip_id is a structure which contains one bit for each OMAP2/3
    CPU type, and on 3430, ES level.  For example, the CHIP_IS_OMAP2420
    bit is set in omap_chip at boot on an OMAP2420.  On OMAP3430ES2, both
    CHIP_IS_OMAP3430 and CHIP_IS_OMAP3430ES2 bits are set.
    
    omap_chip is set in mach-omap2/id.c by _set_omap_chip(). Other
    code should use the omap_chip_is() function to test against omap_chip.
    
    Also, clean up id.c by splitting some code out of
    omap_check_revision() into its own function, _set_system_rev(); and
    converting some debug printk()s into pr_debug().

    ARM: OMAP: CLKFW: Initial debugfs support for omap clock framework
    
    debugfs can provide the infrastructure to trace the dependencies of
    clock tree hierarchy quite visibly. This patch enables to keep track
    of clock tree hierarchy and expose their attributes under each clock
    directry as below:
    
    	omap:~# tree -d -L 2 /debug/clock/omap_32k_fck/
    	/debug/clock/omap_32k_fck/
    	|-- gpt10_fck
    	|-- gpt11_fck
    	|-- gpt1_fck
    	|-- per_32k_alwon_fck
    	|   |-- gpio2_fck
    	|   |-- gpio3_fck
    	|   |-- gpio4_fck
    	|   |-- gpio5_fck
    	|   |-- gpio6_fck
    	|   `-- wdt3_fck
    	|-- ts_fck
    	`-- wkup_32k_fck
    	    |-- gpio1_fck
    	    `-- wdt2_fck
    
    	14 directories
    	omap:~# tree  /debug/clock/omap_32k_fck/gpt10_fck/
    	/debug/clock/omap_32k_fck/gpt10_fck/
    	|-- flags
    	|-- rate
    	`-- usecount
    
    	0 directories, 3 files
    
    Although, compared with David Brownell's small patch, this may look
    bit overkilling, I expect that this debugfs can deal with other PRCM
    complexities at the same time. For example, powerdomain dependencies
    can be expressed by using symbolic links of these clocks if
    powerdomain supports dubgfs as well.

    ARM: OMAP: DMTimer: Use posted mode
    
    This patch adds the use of write posting for the timer.  Previously, every
    write could lock the requestor for almost 3x32KHz cycles.  This patch only
    synchronizes before writes and reads instead of after them and it does
    it on per register basis.  Doing it this way there is some chance to hide
    some of the sync latency.  It also removes some needless reads when
    non-posted mode is there.  With out this fix the read/writes take almost
    2% CPU load @500MHz just waiting on tick timer registers.
    
    Also define new 34xx only registers.

    [GFS2] don't call permission()
    
    GFS2 calls permission() to verify permissions after locks on the files
    have been taken.
    
    For this it's sufficient to call gfs2_permission() instead.  This
    results in the following changes:
    
      - IS_RDONLY() check is not performed
      - IS_IMMUTABLE() check is not performed
      - devcgroup_inode_permission() is not called
      - security_inode_permission() is not called
    
    IS_RDONLY() should be unnecessary anyway, as the per-mount read-only
    flag should provide protection against read-only remounts during
    operations.  do_gfs2_set_flags() has been fixed to perform
    mnt_want_write()/mnt_drop_write() to protect against remounting
    read-only.
    
    IS_IMMUTABLE has been added to gfs2_permission()
    
    Repeating the security checks seems to be pointless, as they don't
    normally change, and if they do, it's independent of the filesystem
    state.

    powerpc/pseries: Update numa association of hotplug memory add for drconf memory
    
    Update the association of a memory section with a numa node that
    occurs during hotplug add of a memory section.  This adds a check in
    the hot_add_scn_to_nid() routine for the
    ibm,dynamic-reconfiguration-memory node in the device tree.  If
    present the new hot_add_drconf_scn_to_nid() routine is invoked, which
    can properly parse the ibm,dynamic-reconfiguration-memory node of the
    device tree and make the proper numa node associations.
    
    This also introduces the valid_hot_add_scn() routine as a helper
    function for code that is common to the hot_add_scn_to_nid() and
    hot_add_drconf_scn_to_nid() routines.

    powerpc/pseries: Split code into helper routines for drconf memory
    
    This splits off several pieces of code that parse the
    ibm,dynamic-reconfiguration-memory node of the device tree into separate
    helper routines.  This is in preparation for the next commit that will
    use these helper routines.  There are no functional changes in this patch.

    powerpc/pseries: Update the device tree correctly for drconf memory add/remove
    
    This updates the device tree manipulation routines so that memory
    add/remove of lmbs represented under the
    ibm,dynamic-reconfiguration-memory node of the device tree invokes the
    hotplug notifier chain.
    
    This change is needed because of the change in the way memory is
    represented under the ibm,dynamic-reconfiguration-memory node.  All lmbs
    are described in the ibm,dynamic-memory property instead of having a
    separate node for each lmb as in previous device tree layouts.  This
    requires the update_node() routine to check for updates to the
    ibm,dynamic-memory property and invoke the hotplug notifier chain.
    
    This also updates the pseries hotplug notifier to be able to gather information
    for lmbs represented under the ibm,dynamic-reconfiguration-memory node and
    have the lmbs added/removed.

    powerpc/pseries: Use base address to derive starting page frame number
    
    Use the base address of the lmb to derive the starting page frame number
    instead of trying to extract it from the drc index of the lmb.  The drc
    index should not be used for this as it will, and did, break.
    
    Until this point, systems that have had memory represented in the device
    tree with a node for each lmb the drc index would (luckily) closely
    track the base address of the lmb.  For example a lmb with a drc index
    of 8000000a would have a base address of a0000000.  This correlation
    allowed the current code to derive the starting page frame number from
    the drc inddex
    
    Device tree layouts where lmbs are represented under the
    ibm,dynamic-reconfiguration-memory node in the ibm,dynamic-memory
    property do not have this correlation between the drc index and base
    address of the lmb.

    powerpc/pseries: Allow phandle to be specified in formats other than decimal
    
    Allow the phandle passed to the /proc/ppc64/ofdt file to be specified
    in formats other than decimal.  This allows us to easily specify phandle
    values in hex that would otherwise appear as negative integers.
    
    This is an issue on systems where the value of
    /proc/device-tree/ibm,dynamic-reconfiguration-memory.ibm,phandle is
    fffffff9.  Having to pass this to the ofdt file as a string results in
    a large negative number, and simple_strtoul() does not handle negative
    numbers.

    powerpc: Fixup lwsync at runtime
    
    To allow for a single kernel image on e500 v1/v2/mc we need to fixup lwsync
    at runtime.  On e500v1/v2 lwsync causes an illop so we need to patch up
    the code.  We default to 'sync' since that is always safe and if the cpu
    is capable we will replace 'sync' with 'lwsync'.
    
    We introduce CPU_FTR_LWSYNC as a way to determine at runtime if this is
    needed.  This flag could be moved elsewhere since we dont really use it
    for the normal CPU_FTR purpose.
    
    Finally we only store the relative offset in the fixup section to keep it
    as small as possible rather than using a full fixup_entry.

    Remove BKL from remote_llseek v2
    
    - Replace remote_llseek with generic_file_llseek_unlocked (to force compilation
    failures in all users)
    - Change all users to either use generic_file_llseek_unlocked directly or
    take the BKL around. I changed the file systems who don't use the BKL
    for anything (CIFS, GFS) to call it directly. NCPFS and SMBFS and NFS
    take the BKL, but explicitely in their own source now.
    
    I moved them all over in a single patch to avoid unbisectable sections.
    
    Open problem: 32bit kernels can corrupt fpos because its modification
    is not atomic, but they can do that anyways because there's other paths who
    modify it without BKL.
    
    Do we need a special lock for the pos/f_version = 0 checks?
    
    Trond says the NFS BKL is likely not needed, but keep it for now
    until his full audit.
    
    v2: Use generic_file_llseek_unlocked instead of remote_llseek_unlocked
        and factor duplicated code (suggested by hch)

    avr32: Power Management support ("standby" and "mem" modes)
    
    Implement Standby support. In this mode, we'll suspend all drivers,
    put the SDRAM in self-refresh mode and switch off the HSB bus
    ("frozen" mode.)
    
    Implement Suspend-to-mem support. In this mode, we suspend all
    drivers, put the SDRAM into self-refresh mode and switch off all
    internal clocks except the 32 kHz oscillator ("stop" mode.)
    
    The lowest-level suspend code runs from a small portion of SRAM
    allocated at startup time. This gets rid of a small potential race
    with the SDRAM where we might try to enter self-refresh mode in the
    middle of an icache burst. We also relocate all interrupt and
    exception handlers to SRAM during the small window when we enter and
    exit the low-power modes.
    
    We don't need to do any special tricks to start and stop the PLL. The
    main clock is automatically gated by hardware until the PLL is stable.

    Expand the per-process PGDs so that they cover the kernel virtual
    memory area as well. This simplifies the TLB miss handler fastpath
    since it doesn't have to check for kernel addresses anymore.
    
    If a TLB miss happens on a kernel address and a second-level page
    table can't be found, we check swapper_pg_dir and copy the PGD entry
    into the user PGD if it can be found there.

    avr32: Store virtual addresses in the PGD
    
    Instead of storing physical addresses along with page flags in the
    PGD, store virtual addresses and use NULL to indicate a not present
    second-level page table. A non-page-aligned page table indicates a bad
    PMD.
    
    This simplifies the TLB miss handler since it no longer has to check
    the Present bit and no longer has to convert the PGD entry from
    physical to virtual address. Instead, it has to check for a NULL
    entry, which is slightly cheaper than either.

    avr32: Clean up and optimize the TLB operations
    
    This and the following patches aim to optimize the code dealing with
    page tables and TLB operations. Each patch reduces the time it takes
    to gzip a 16 MB file slightly, but I expect things like fork() and
    mmap() will improve somewhat more.
    
    This patch deals with the low-level TLB operations:
    
      * Remove unused _TLBEHI_I define
      * Use gcc builtins instead of inline assembly
      * Remove a few unnecessary pipeline flushes and nops
      * Introduce NR_TLB_ENTRIES define and use it instead of hardcoding it
        to 32 a few places throughout the code.
      * Use sysreg bitops instead of hardcoded shifts and masks
      * Make a few needlessly global functions static

    powerpc: Keep 3 high personality bytes across exec
    
    Currently when a 32 bit process is exec'd on a powerpc 64 bit host the
    value in the top three bytes of the personality is clobbered.  patch
    adds a check in the SET_PERSONALITY macro that will carry all the
    values in the top three bytes across the exec.
    
    These three bytes currently carry flags to disable address randomisation,
    limit the address space, force zeroing of an mmapped page, etc.  Should an
    application set any of these bits they will be maintained and honoured on
    homogeneous environment but discarded and ignored on a heterogeneous
    environment.  So if an application requires all mmapped pages to be initialised
    to zero and a wrapper is used to setup the personality and exec the target,
    these flags will remain set on an all 32 or all 64 bit envrionment, but they
    will be lost in the exec on a mixed 32/64 bit environment.  Losing these bits
    means that the same application would behave differently in different
    environments.  Tested on a POWER5+ machine with 64bit kernel and a mixed
    64/32 bit user space.

    x86: remove arbitrary ELF section limit in i386 relocatable kernel
    
    Impact: build failure in maximal configurations
    
    The 32-bit x86 relocatable kernel requires an auxilliary host program
    to process the relocations.  This program had a hard-coded arbitrary
    limit of a 100 ELF sections.  Instead of a hard-coded limit, allocate
    the structures dynamically.

    powerpc: Add 64 bit version of huge_ptep_set_wrprotect
    
    The implementation of huge_ptep_set_wrprotect() directly calls
    ptep_set_wrprotect() to mark a hugepte write protected.  However this
    call is not appropriate on ppc64 kernels as this is a small page only
    implementation.  This can lead to the hash not being flushed correctly
    when a mapping is being converted to COW, allowing processes to continue
    using the original copy.
    
    Currently huge_ptep_set_wrprotect() unconditionally calls
    ptep_set_wrprotect().  This is fine on ppc32 kernels as this call is
    generic.  On 64 bit this is implemented as:
    
    	pte_update(mm, addr, ptep, _PAGE_RW, 0);
    
    On ppc64 this last parameter is the page size and is passed directly on
    to hpte_need_flush():
    
    	hpte_need_flush(mm, addr, ptep, old, huge);
    
    And this directly affects the page size we pass to flush_hash_page():
    
    	flush_hash_page(vaddr, rpte, psize, ssize, 0);
    
    As this changes the way the hash is calculated we will flush the wrong
    pages, potentially leaving live hashes to the original page.
    
    Move the definition of huge_ptep_set_wrprotect() to the 32/64 bit specific
    headers.

    powerpc: Prevent memory corruption due to cache invalidation of unaligned DMA buffer
    
    On PowerPC processors with non-coherent cache architectures the DMA
    subsystem calls invalidate_dcache_range() before performing a DMA read
    operation.  If the address and length of the DMA buffer are not aligned
    to a cache-line boundary this can result in memory outside of the DMA
    buffer being invalidated in the cache.  If this memory has an
    uncommitted store then the data will be lost and a subsequent read of
    that address will result in an old value being returned from main memory.
    
    Only when the DMA buffer starts on a cache-line boundary and is an exact
    mutiple of the cache-line size can invalidate_dcache_range() be called,
    otherwise flush_dcache_range() must be called.  flush_dcache_range()
    will first flush uncommitted writes, and then invalidate the cache.

    powerpc: Add VSX context save/restore, ptrace and signal support
    
    This patch extends the floating point save and restore code to use the
    VSX load/stores when VSX is available.  This will make FP context
    save/restore marginally slower on FP only code, when VSX is available,
    as it has to load/store 128bits rather than just 64bits.
    
    Mixing FP, VMX and VSX code will get constant architected state.
    
    The signals interface is extended to enable access to VSR 0-31
    doubleword 1 after discussions with tool chain maintainers.  Backward
    compatibility is maintained.

    VSX has 64 128bit registers.  The first 32 regs overlap with the FP
    registers and hence extend them with and additional 64 bits.  The
    second 32 regs overlap with the VMX registers.
    
    This commit introduces the thread_struct changes required to reflect
    this register layout.  Ptrace and signals code is updated so that the
    floating point registers are correctly accessed from the thread_struct
    when CONFIG_VSX is enabled.

    powerpc: Introduce infrastructure for feature sections with alternatives
    
    The current feature section logic only supports nop'ing out code, this means
    if you want to choose at runtime between instruction sequences, one or both
    cases will have to execute the nop'ed out contents of the other section, eg:
    
    BEGIN_FTR_SECTION
    	or	1,1,1
    END_FTR_SECTION_IFSET(FOO)
    BEGIN_FTR_SECTION
    	or	2,2,2
    END_FTR_SECTION_IFCLR(FOO)
    
    and the resulting code will be either,
    
    	or	1,1,1
    	nop
    
    or,
    	nop
    	or	2,2,2
    
    For small code segments this is fine, but for larger code blocks and in
    performance criticial code segments, it would be nice to avoid the nops.
    This commit starts to implement logic to allow the following:
    
    BEGIN_FTR_SECTION
    	or	1,1,1
    FTR_SECTION_ELSE
    	or	2,2,2
    ALT_FTR_SECTION_END_IFSET(FOO)
    
    and the resulting code will be:
    
    	or	1,1,1
    or,
    	or	2,2,2
    
    We achieve this by extending the existing FTR macros. The current feature
    section semantic just becomes a special case, ie. if the else case is empty
    we nop out the default case.
    
    The key limitation is that the size of the else case must be less than or
    equal to the size of the default case. If the else case is smaller the
    remainder of the section is nop'ed.
    
    We let the linker put the else case code in with the rest of the text,
    so that relative branches from the else case are more likley to link,
    this has the disadvantage that we can't free the unused else cases.
    
    This commit introduces the required macro and linker script changes, but
    does not enable the patching of the alternative sections.
    
    We also need to update two hand-made section entries in reg.h and timex.h

    one version of MAKE_FTR_SECTION_ENTRY().

    powerpc: Consolidate CPU and firmware feature fixup macros
    
    The CPU and firmware feature fixup macros are currently spread across
    three files, firmware.h, cputable.h and asm-compat.h.  Consolidate them
    into their own file, feature-fixups.h

    powerpc: Split out do_feature_fixups() from cputable.c
    
    The logic to patch CPU feature sections lives in cputable.c, but these days
    it's used for CPU features as well as firmware features.  Move it into
    it's own file for neatness and as preparation for some additions.
    
    While we're moving the code, we pull the loop body logic into a separate
    routine, and remove a comment which doesn't apply anymore.

    powerpc: Make create_branch() return errors if the branch target is too large
    
    If you pass a target value to create_branch() which is more than 32MB - 4,
    or - 32MB away from the branch site, then it's impossible to create an
    immediate branch.  The current code doesn't check, which will lead to us
    creating a branch to somewhere else - which is bad.
    
    For code that cares to check we return 0, which is easy to check for, and
    for code that doesn't at least we'll be creating an illegal instruction,
    rather than a branch to some random address.

    powerpc: Allow create_branch() to return errors
    
    Currently create_branch() creates a branch instruction for you, and
    patches it into the call site.  In some circumstances it would be nice
    to be able to create the instruction and patch it later, and also some
    code might want to check for errors in the branch creation before
    doing the patching.  A future commit will change create_branch() to
    check for errors.
    
    For callers that don't care, replace create_branch() with
    patch_branch(), which just creates the branch and patches it directly.
    
    While we're touching all the callers, change to using unsigned int *,
    as this seems to match usage better.  That allows (and requires) us to
    remove the volatile in the definition of vector in powermac/smp.c and
    mpc86xx_smp.c, that's correct because now that we're passing vector as
    an unsigned int * the compiler knows that it's value might change
    across the patch_branch() call.

    drivers/macintosh/smu.c: Improve error handling
    
    This makes two changes:
    
    * As noted by Akinobu Mita in patch
    b1fceac2b9e04d278316b2faddf276015fc06e3b, alloc_bootmem never returns NULL
    and always returns a zeroed region of memory.  Thus the error checking code
    and memset after the call to alloc_bootmem are not necessary.
    
    * The old error handling code consisted of setting a global variable to
    NULL and returning an error code, which could cause previously allocated
    resources never to be freed.  The patch adds calls to appropriate resource
    deallocation functions.

    powerpc: Only demote individual slices rather than whole process
    
    At present, if we have a kernel with a 64kB page size, and some
    process maps something that has to be mapped with 4kB pages (such as a
    cache-inhibited mapping on POWER5+, or the eHCA infiniband queue-pair
    pages), we change the process to use 4kB pages everywhere.  This hurts
    the performance of HPC programs that access eHCA from userspace.
    
    With this patch, the kernel will only demote the slice(s) containing
    the eHCA or cache-inhibited mappings, leaving the remaining slices
    able to use 64kB hardware pages.
    
    This also changes the slice_get_unmapped_area code so that it is
    willing to place a 64k-page mapping into (or across) a 4k-page slice
    if there is no better alternative, i.e. if the program specified
    MAP_FIXED or if there is not sufficient space available in slices that
    are either empty or already have 64k-page mappings in them.

    [ARM] Orion: make PCI handling code deal with Cardbus slots
    
    The Cardbus connector does not have an IDSEL signal, and Cardbus
    cards are always the intended target of configuration transactions
    on their local PCI bus.  This means that if the Orion's PCI bus
    signals are hooked up to a Cardbus slot, the same set of PCI
    functions will will appear 31 times, for each of the PCI device
    IDs 1-31 (ID 0 is the host bridge).
    
    This patch adds a function to the Orion PCI handling code that board
    support code can call to enable Cardbus mode.  When Cardbus mode is
    enabled, configuration transactions on the PCI local bus are only
    allowed to PCI IDs 0 (host bridge) and 1 (cardbus device).

    powerpc: Get rid of bitfields in ppc_bat struct
    
    While working on the 36-bit physical support, I noticed that there
    was exactly one line of code that actually referenced the bitfields.
    So I got rid of them and redefined ppc_bat as a struct of 2 u32's:
    batu and batl.  I also got rid of the previous union that held the
    bitfield structs and a word representation of the batu/l values.
    
    This seems like a nicer solution than adding in a bunch of
    new bitfields to support extended bat addressing that would never
    get used, and just leaving the struct as-is would have been

    powerpc: Change BAT code to use phys_addr_t
    
    Currently, the physical address is an unsigned long, but it should
    be phys_addr_t in set_bat, [v/p]_mapped_by_bat.  Also, create a
    macro that can convert a large physical address into the correct
    format for programming the BAT registers.

    powerpc: Implement OF PCI address accessors stubs for CONFIG_PCI=n
    
    To avoid "#ifdef CONFIG_PCI" in the drivers we should provide stubs in
    place of OF PCI address accessors.
    
    Without these stubs build breaks for drivers not strictly requiring PCI,
    for example CONFIG_FB_OF=y without CONFIG_PCI:
    
      LD      .tmp_vmlinux1
    drivers/built-in.o: In function `offb_map_reg':
    offb.c:(.text+0x6e7c): undefined reference to `of_get_pci_address'
    
    OF PCI IRQ accessors require pci_dev argument, so drivers using PCI
    IRQs should depend on CONFIG_PCI anyway.

    x86: setup: issue a null command after enabling A20 via KBC
    
    Apparently, DOS and possibly other legacy operating systems issued a
    null command to the keyboard controller after toggling A20,
    specifically "pulse output pins" with no output pins specified.  This
    was presumably done for synchronization reasons.  This has made it
    into at least the UHCI spec, and it has been found to cause
    compatibility problems when "legacy USB" is enabled (which it almost
    always is) to not have this byte sent.
    
    It is *NOT* clear if any of these compatibility problems has any
    effect on Linux.  However, for maximum compatibility, issue this null
    command after togging A20 through the KBC.

    PCI: remove unused arch pcibios_update_resource() functions
    
    Russell King did the following back in 2003:
    
    <--  snip  -->
    
        [PCI] pci-9: Kill per-architecture pcibios_update_resource()
    
        Kill pcibios_update_resource(), replacing it with pci_update_resource().
        pci_update_resource() uses pcibios_resource_to_bus() to convert a
        resource to a device BAR - the transformation should be exactly the
        same as the transformation used for the PCI bridges.
    
        pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to
        set the high 32-bits to anything non-zero - currently no architecture
        attempts to do something different.  If anyone cares, please fix; I'm
        going to reflect current behaviour for the time being.
    
        Ivan pointed out the following architectures need to examine their
        pcibios_update_resource() implementation - they should make sure that
        this new implementation does the right thing.  #warning's have been
        added where appropriate.
    
            ia64
            mips
            mips64
    
        This cset also includes a fix for the problem reported by AKPM where
        64-bit arch compilers complain about the resource mask being placed
        in a u32.
    
    <--  snip  -->
    
    This patch removes the unused pcibios_update_resource() functions the
    kernel gained since, from FRV, m68k, mips & sh architectures.

    pciehp: use get_service_data
    
    Current pciehp driver saves its private data pointer into pci_dev
    structure using pci_set_drvdata()/pci_get_drvdata(). But because
    pciehp is not a pci device driver but a PCI Express service driver, it
    should save its private data pointer into pcie_device structure using
    set_service_data()/get_service_data().

    pciehp: remove needless command completed interrupt setting
    
    Currently, pciehp driver enables command completed interrupt as follows.
    
    (1) Don't enable at initialization.
    (2) Enable command completed interrupt whenever pciehp issues a
        command, if the command doesn't attempt to disable the interrupt.
    (3) Disable command completed interrupt at driver unloading.
    
    Once we enable command completed interrupt, we don't need to re-enable
    it for every command. So we can simplify above steps as follows:
    
    (1) Enable command completed interrupt at initialization.
    (2) No special sequence for command completed interrupt.
    (3) Disable command completed interrupt at driver unloading.

    pciehp: fix interrupt initialization
    
    Current pciehp driver's intialization sequence is as follows:
    
    (1) initialize controller data structure
    (2) install interrupt handler
    (3) enable software notification
    (4) initialize controller specific slot data structure
    (5) initialize generic slot data structure and register it to pci hotplug core
    
    The interrupt handler of pciehp assumes that controller specific slot
    data structure is already initialized. However, it is installed at (2)
    before initializing controller specific slot data structure at
    (4). Because of this, pciehp driver cannot handle the following cases
    properly.
    
    - If devices that shares IRQ with pciehp raise interrupts between (2) and (4).
    - If hotplug events (e.g. MRL open) happen between (3) and (4).
    
    We already have a workaround for this problem ("pciehp: fix NULL
    dereference in interrupt handler: dbd79aed1aea2bece0bf43cc2ff3b2f9baf48a08).
    But we still need fundamental fix.
    
    This patch fix the problem by changing the initilization sequence as follows:
    
    (1) initialize controller data structure
    (2) initialize controller specific slot data structure
    (3) install interrupt handler
    (4) enable software notification
    (5) initialize generic slot data structure and register it to pci hotplug core

    x86: don't destroy %rbp on kernel-mode faults
    
    From the code:
    
        "B stepping K8s sometimes report an truncated RIP for IRET exceptions
        returning to compat mode. Check for these here too."
    
    The code then proceeds to truncate the upper 32 bits of %rbp. This means
    that when do_page_fault() is finally called, its prologue,
    
        do_page_fault:
            push %rbp
            movl %rsp, %rbp
    
    will put the truncated base pointer on the stack. This means that the
    stack tracer will not be able to follow the base-pointer changes and
    will see all subsequent stack frames as unreliable.
    
    This patch changes the code to use a different register (%rcx) for the
    checking and leaves %rbp untouched.

    at32ap700x spi: enable pullups on MISO
    
    This is a minor tweak to the at32ap700x pin configuration for the SPI
    input pin (MISO), enabling the on-chip weak pullup (typical 190K) to
    
      (a) ensure a fixed data value for missing or input-only slaves;
    
      (b) prevent power waste associated with inputs floating near VDDIO/2.
    
    Atmel's boards have no external pullup or pulldown on these pins, so
    it's unlikely other boards would address these issues with external
    pulldowns.  Were there trouble, board-specific code could turn off
    the relevant pullup(s).

    A signal handler should be able to change the signal stack used for the

    sched: fix task_h_load()
    
    Currently task_h_load() computes the load of a task and uses that to either
    subtract it from the total, or add to it.
    
    However, removing or adding a task need not have any effect on the total load
    at all. Imagine adding a task to a group that is local to one cpu - in that
    case the total load of that cpu is unaffected.
    
    So properly compute addition/removal:
    
     s_i = S * rw_i / \Sum_j rw_j
     s'_i = S * (rw_i + wl) / (\Sum_j rw_j + wg)
    
    then s'_i - s_i gives the change in load.
    
    Where s_i is the shares for cpu i, S the group weight, rw_i the runqueue weight
    for that cpu, wl the weight we add (subtract) and wg the weight contribution to
    the runqueue.

    sched: fix load scaling in group balancing
    
    doing the load balance will change cfs_rq->load.weight (that's the whole point)
    but since that's part of the scale factor, we'll scale back with a different
    amount.
    
    Weight getting smaller would result in an inflated moved_load which causes
    it to stop balancing too soon.

    find_busiest_group() has some assumptions about task weight being in the

    by replacing it with the average task weight, which will adapt the situation.

    sched: simplify the group load balancer
    
    While thinking about the previous patch - I realized that using per domain
    aggregate load values in load_balance_fair() is wrong. We should use the
    load value for that CPU.
    
    By not needing per domain hierarchical load values we don't need to store
    per domain aggregate shares, which greatly simplifies all the math.
    
    It basically falls apart in two separate computations:
     - per domain update of the shares
     - per CPU update of the hierarchical load
    
    Also get rid of the move_group_shares() stuff - just re-compute the shares
    again after a successful load balance.

    It was observed that in __update_group_shares_cpu()
    
      rq_weight > aggregate()->rq_weight
    
    This is caused by forks/wakeups in between the initial aggregate pass and
    locking of the RQs for load balance. To avoid this situation partially re-do
    the aggregation once we have the RQs locked (which avoids new tasks from
    appearing).

    sched: fix calc_delta_asym()
    
    calc_delta_asym() is supposed to do the same as calc_delta_fair() except
    linearly shrink the result for negative nice processes - this causes them
    to have a smaller preemption threshold so that they are more easily preempted.
    
    The problem is that for task groups se->load.weight is the per cpu share of
    the actual task group weight; take that into account.
    
    Also provide a debug switch to disable the asymmetry (which I still don't
    like - but it does greatly benefit some workloads)
    
    This would explain the interactivity issues reported against group scheduling.

    [GFS2] Remove all_list from lock_dlm
    
    I discovered that we had a list onto which every lock_dlm
    lock was being put. Its only function was to discover whether
    we'd got any locks left after umount. Since there was already
    a counter for that purpose as well, I removed the list. The
    saving is sizeof(struct list_head) per glock - well worth
    having.

    [GFS2] Remove remote lock dropping code
    
    There are several reasons why this is undesirable:
    
     1. It never happens during normal operation anyway
     2. If it does happen it causes performance to be very, very poor
     3. It isn't likely to solve the original problem (memory shortage
        on remote DLM node) it was supposed to solve
     4. It uses a bunch of arbitrary constants which are unlikely to be
        correct for any particular situation and for which the tuning seems
        to be a black art.
     5. In an N node cluster, only 1/N of the dropped locked will actually
        contribute to solving the problem on average.
    
    So all in all we are better off without it. This also makes merging
    the lock_dlm module into GFS2 a bit easier.

    [GFS2] kernel panic mounting volume
    
    This patch fixes Red Hat bugzilla bug 450156.
    
    This started with a not-too-improbable mount failure because the
    locking protocol was never set back to its proper "lock_dlm" after the
    system was rebooted in the middle of a gfs2_fsck.  That left a
    (purposely) invalid locking protocol in the superblock, which caused an
    error when the file system was mounted the next time.
    
    When there's an error mounting, vfs calls DQUOT_OFF, which calls
    vfs_quota_off which calls gfs2_sync_fs.  Next, gfs2_sync_fs calls
    gfs2_log_flush passing s_fs_info.  But due to the error, s_fs_info
    had been previously set to NULL, and so we have the kernel oops.
    
    My solution in this patch is to test for the NULL value before passing
    it.  I tested this patch and it fixes the problem.

    [GFS2] Revise readpage locking
    
    The previous attempt to fix the locking in readpage failed due
    to the use of a "try lock" which resulted in occasional high
    cpu usage during testing (due to repeated tries) and also it
    did not resolve all the ordering problems wrt the transaction
    lock (although it did solve all the inode lock ordering problems).
    
    This patch avoids the problem by unlocking the page and getting the
    locks in the correct order. This means that we have to retest the
    page to ensure that it hasn't changed when we relock the page.
    
    This now passes the tests which were previously failing.

    [GFS2] No lock_nolock
    
    This patch merges the lock_nolock module into GFS2 itself. As well as removing
    some of the overhead of the module, it also means that its now impossible to
    build GFS2 without a lock module (which would be a pointless thing to do
    anyway).
    
    We also plan to merge lock_dlm into GFS2 in the future, but that is a more
    tricky task, and will therefore be a separate patch.

    [GFS2] Fix ordering bug in lock_dlm
    
    This looks like a lot of change, but in fact its not. Mostly its
    things moving from one file to another. The change is just that
    instead of queuing lock completions and callbacks from the DLM
    we now pass them directly to GFS2.
    
    This gives us a net loss of two list heads per glock (a fair
    saving in memory) plus a reduction in the latency of delivering
    the messages to GFS2, plus we now have one thread fewer as well.
    There was a bug where callbacks and completions could be delivered
    in the wrong order due to this unnecessary queuing which is fixed
    by this patch.

    [GFS2] Clean up the glock core
    
    This patch implements a number of cleanups to the core of the
    GFS2 glock code. As a result a lot of code is removed. It looks
    like a really big change, but actually a large part of this patch
    is either removing or moving existing code.
    
    There are some new bits too though, such as the new run_queue()
    function which is considerably streamlined. Highlights of this
    patch include:
    
     o Fixes a cluster coherency bug during SH -> EX lock conversions
     o Removes the "glmutex" code in favour of a single bit lock
     o Removes the ->go_xmote_bh() for inodes since it was duplicating
       ->go_lock()
     o We now only use the ->lm_lock() function for both locks and
       unlocks (i.e. unlock is a lock with target mode LM_ST_UNLOCKED)
     o The fast path is considerably shortly, giving performance gains
       especially with lock_nolock
     o The glock_workqueue is now used for all the callbacks from the DLM
       which allows us to simplify the lock_dlm module (see following patch)
     o The way is now open to make further changes such as eliminating the two
       threads (gfs2_glockd and gfs2_scand) in favour of a more efficient
       scheme.
    
    This patch has undergone extensive testing with various test suites
    so it should be pretty stable by now.

    friends, and adds support for smp_call_function_single().
    
    ppc loses the timeout functionality of smp_call_function_mask() with
    this change, as the generic code does not provide that.

    Add generic helpers for arch IPI function calls
    
    This adds kernel/smp.c which contains helpers for IPI function calls. In
    addition to supporting the existing smp_call_function() in a more efficient
    manner, it also adds a more scalable variant called smp_call_function_single()
    for calling a given function on a single CPU only.
    
    The core of this is based on the x86-64 patch from Nick Piggin, lots of
    changes since then. "Alan D. Brunelle" <Alan.Brunelle@hp.com> has
    contributed lots of fixes and suggestions as well. Also thanks to
    Paul E. McKenney <paulmck@linux.vnet.ibm.com> for reviewing RCU usage
    and getting rid of the data allocation fallback deadlock.

    powerpc/kprobes: Some minor fixes
    
    * Mark __flush_icache_range as a function that can't be probed since its
      used by the kprobe code.
    
    * Fix an issue with single stepping and async exceptions.  We need to
      ensure that we dont get an async exception (external, decrementer, etc)
      while we are attempting to single step the probe point.
    
      Added a check to ensure we only handle a single step if its really
      intended for the instruction in question.

    rcu: make rcutorture even more vicious: invoke RCU readers from irq handlers (timers)
    
    This patch allows torturing RCU from irq handlers (timers, in this case).
    A new module parameter irqreader enables such additional torturing,
    and is enabled by default.  Variants of RCU that do not tolerate readers
    being called from irq handlers (e.g., SRCU) ignore irqreader.

    [ALSA] Revert "alsa: add annotations to bitwise type snd_pcm_hw_param_t"
    
    This reverts commit 36b34d2437104f323e09d7c6af6451d3c0b9c0cd.
    
    From: Al Viro <viro@ZenIV.linux.org.uk>
    
    WIW, *all* this stuff is not bitwise at all.  For crying out loud, half
    of these types are routinely used as array indices and loop variables...
    
    If anything, we want a different set of allowed operations - subtraction
    between elements of type (yielding integer), addition/subtraction of
    integer types not bigger than ours (yielding our type), comparisons,
    assignments (=, +=, -=, passing to function as argument, return from
    function, initializers) and second/third arguments in ?:.  With 0 *not*
    being allowed as a constant of such type.
    
    It's not bitwise; we may use the same infrastructure in sparse, but it
    should be a separate class of types (__attribute__((affine))).
    
    dma_addr_t is another candidate for the same treatment, but there we'll
    need helpers for conversions to hw-acceptable form (dma_to_le32(), etc.)
    and gradual conversion of drivers.
    
    ALSA ones and pm mess are absolutely straightforward cases, though.

    PCI: use dev_printk when possible
    
    Convert printks to use dev_printk().
    
    I converted pr_debug() to dev_dbg().  Both use KERN_DEBUG and are enabled
    only when DEBUG is defined.
    
    I converted printk(KERN_DEBUG) to dev_printk(KERN_DEBUG), not to dev_dbg(),
    because dev_dbg() is only enabled when DEBUG is defined.
    
    I converted DBG(KERN_INFO) (only in setup-bus.c) to dev_info().  The DBG()
    name makes it sound like debug, but it's been enabled forever, so dev_info()
    preserves the previous behavior.
    
    I tried to make the resource assignment formats more consistent, e.g.,
      "BAR %d: got res [%#llx-%#llx] bus [%#llx-%#llx] flags %#lx\n"
    instead of sometimes using "start-end" and sometimes using "size@start".
    I'm not attached to one or the other; I'd just like them consistent.

    xen: add mechanism to extend existing multicalls
    
    Some Xen hypercalls accept an array of operations to work on.  In
    general this is because its more efficient for the hypercall to the
    work all at once rather than as separate hypercalls (even batched as a
    multicall).
    
    This patch adds a mechanism (xen_mc_extend_args()) to allocate more
    argument space to the last-issued multicall, in order to extend its
    argument list.
    
    The user of this mechanism is xen/mmu.c, which uses it to extend the
    args array of mmu_update.  This is particularly valuable when doing
    the update for a large mprotect, which goes via
    ptep_modify_prot_commit(), but it also manages to batch updates to
    pgd/pmds as well.

    xen: implement ptep_modify_prot_start/commit
    
    Xen has a pte update function which will update a pte while preserving
    its accessed and dirty bits.  This means that ptep_modify_prot_start() can be
    implemented as a simple read of the pte value.  The hardware may
    update the pte in the meantime, but ptep_modify_prot_commit() updates it while
    preserving any changes that may have happened in the meantime.
    
    The updates in ptep_modify_prot_commit() are batched if we're currently in lazy
    mmu mode.
    
    The mmu_update hypercall can take a batch of updates to perform, but
    this code doesn't make particular use of that feature, in favour of
    using generic multicall batching to get them all into the hypervisor.
    
    The net effect of this is that each mprotect pte update turns from two
    expensive trap-and-emulate faults into they hypervisor into a single
    hypercall whose cost is amortized in a batched multicall.

    mm: add a ptep_modify_prot transaction abstraction
    
    This patch adds an API for doing read-modify-write updates to a pte's
    protection bits which may race against hardware updates to the pte.
    After reading the pte, the hardware may asynchonously set the accessed
    or dirty bits on a pte, which would be lost when writing back the
    modified pte value.
    
    The existing technique to handle this race is to use
    ptep_get_and_clear() atomically fetch the old pte value and clear it
    in memory.  This has the effect of marking the pte as non-present,
    which will prevent the hardware from updating its state.  When the new
    value is written back, the pte will be present again, and the hardware
    can resume updating the access/dirty flags.
    
    When running in a virtualized environment, pagetable updates are
    relatively expensive, since they generally involve some trap into the
    hypervisor.  To mitigate the cost of these updates, we tend to batch
    them.
    
    However, because of the atomic nature of ptep_get_and_clear(), it is
    inherently non-batchable.  This new interface allows batching by
    giving the underlying implementation enough information to open a
    transaction between the read and write phases:
    
    ptep_modify_prot_start() returns the current pte value, and puts the
      pte entry into a state where either the hardware will not update the
      pte, or if it does, the updates will be preserved on commit.
    
    ptep_modify_prot_commit() writes back the updated pte, makes sure that
      any hardware updates made since ptep_modify_prot_start() are
      preserved.
    
    ptep_modify_prot_start() and _commit() must be exactly paired, and
    used while holding the appropriate pte lock.  They do not protect
    against other software updates of the pte in any way.
    
    The current implementations of ptep_modify_prot_start and _commit are
    functionally unchanged from before: _start() uses ptep_get_and_clear()
    fetch the pte and zero the entry, preventing any hardware updates.
    _commit() simply writes the new pte value back knowing that the
    hardware has not updated the pte in the meantime.
    
    The only current user of this interface is mprotect

    x86: use cpu_khz for loops_per_jiffy calculation
    
    On the x86 platform we can use the value of tsc_khz computed during tsc
    calibration to calculate the loops_per_jiffy value. Its very important
    to keep the error in lpj values to minimum as any error in that may
    result in kernel panic in check_timer. In virtualization environment, On
    a highly overloaded host the guest delay calibration may sometimes
    result in errors beyond the ~50% that timer_irq_works can handle,
    resulting in the guest panicking.
    
    Does some formating changes to lpj_setup code to now have a single
    printk to print the bogomips value.
    
    We do this only for the boot processor because the AP's can have
    different base frequencies or the BIOS might boot a AP at a different
    frequency.

    ftrace: freeze kprobe'd records
    
    Let records identified as being kprobe'd be marked as "frozen". The trouble
    with records which have a kprobe installed on their mcount call-site is
    that they don't get updated. So if such a function which is currently being
    traced gets its tracing disabled due to a new filter rule (or because it
    was added to the notrace list) then it won't be updated and continue being
    traced. This patch allows scanning of all frozen records during tracing to
    check if they should be traced.

    The Marvell Discovery Duo (MV78xx0) is a family of ARM SoCs featuring
    (depending on the model) one or two Feroceon CPU cores with 512K of L2
    cache and VFP coprocessors running at (depending on the model) between
    800 MHz and 1.2 GHz, and features a DDR2 controller, two PCIe
    interfaces that can each run either in x4 or quad x1 mode, three USB
    2.0 interfaces, two 3Gb/s SATA II interfaces, a SPI interface, two
    TWSI interfaces, a crypto accelerator, IDMA/XOR engines, a SPI
    interface, four UARTs, and depending on the model, two or four gigabit
    ethernet interfaces.

    [ARM] Feroceon: L2 cache support
    
    This patch adds support for the unified Feroceon L2 cache controller
    as found in e.g. the Marvell Kirkwood and Marvell Discovery Duo
    families of ARM SoCs.
    
    Note that:
    
    - Page table walks are outer uncacheable on Kirkwood and Discovery
      Duo, since the ARMv5 spec provides no way to indicate outer
      cacheability of page table walks (specifying it in TTBR[4:3] is
      an ARMv6+ feature).
    
      This requires adding L2 cache clean instructions to
      proc-feroceon.S (dcache_clean_area(), set_pte()) as well as to
      tlbflush.h ({flush,clean}_pmd_entry()).  The latter case is handled
      by defining a new TLB type (TLB_FEROCEON) which is almost identical
      to the v4wbi one but provides a TLB_L2CLEAN_FR flag.
    
    - The Feroceon L2 cache controller supports L2 range (i.e. 'clean L2
      range by MVA' and 'invalidate L2 range by MVA') operations, and this
      patch uses those range operations for all Linux outer cache
      operations, as they are faster than the regular per-line operations.
    
      L2 range operations are not interruptible on this hardware, which
      avoids potential livelock issues, but can be bad for interrupt
      latency, so there is a compile-time tunable (MAX_RANGE_SIZE) which
      allows you to select the maximum range size to operate on at once.
      (Valid range is between one cache line and one 4KiB page, and must
      be a multiple of the line size.)

    [ARM] Feroceon: speed up flushing of the entire cache
    
    Flushing the L1 D cache with a test/clean/invalidate loop is very
    easy in software, but it is not the quickest way of doing it, as
    there is a lot of overhead involved in re-scanning the cache from

    This patch makes proc-feroceon.S use "clean+invalidate by set/way"
    loops according to possible cache configuration of Feroceon CPUs
    (either direct-mapped or 4-way set associative).

    [ARM] Orion: move EHCI/I2C/UART peripheral init into board code
    
    This patch moves initialisation of EHCI/I2C/UART platform devices
    from the common orion5x_init() into the board support code.
    
    The rationale behind this is that only the board support code knows
    whether certain peripherals have been brought out on the board, and
    not initialising peripherals that haven't been brought out is
    desirable for example:
    - to reduce user confusion (e.g. seeing both 'eth0' and 'eth1'
      appear while there is only one ethernet port on the board); and
    - to allow for future power savings (peripherals that have not
      been brought out can be clock gated off entirely).

    [ARM] Orion: top-level IRQs are level-triggered
    
    Make it clear that Orion top-level IRQs are level-triggered.  This
    means that we don't need an ->ack() handler, or at least, we don't
    need the ->ack() handler (or the acking part of the ->mask_ack()
    handler) to actually do anything.
    
    Given that, we might as well point our ->mask_ack() handler at the
    ->mask() handler instead of providing a dummy ->ack() handler, since
    providing a ->mask_ack() handler on level IRQ sources will prevent
    ->ack() from ever being called.

    [ARM] Orion: DRAM mapping granularity is 64KiB, not 16MiB
    
    The DRAM base address and size fields in the CPU's MBUS bridge have
    64KiB granularity, instead of the currently used 16MiB.  Since all
    of the currently supported MBUS peripherals support 64KiB granularity
    as well, this patch changes the Orion address map code to stop
    rounding base addresses down and sizes up to multiples of 16MiB.

    [ARM] Orion: make window setup a little more safe
    
    Currently, Orion window setup uses hardcoded window indexes for each
    of the boot/cs0/cs1/cs2/PCIe WA windows.  The static window allocation
    used can clash if board support code will ever attempt to configure
    both a dev2 and a PCIe WA window, as both of those use CPU mbus window
    #7 at present.
    
    This patch keeps track of the last used window, and opens subsequently
    requested windows sequentially, starting from 4.  (Windows 0-3 are used
    as MEM/IO windows for the PCI/PCIe buses.)

    [ARM] cache align destination pointer when copying memory for some processors
    
    The implementation for memory copy functions on ARM had a (disabled)
    provision for aligning the source pointer before loading registers with
    data.  Turns out that aligning the _destination_ pointer is much more
    useful, as the read side is already sufficiently helped with the use of
    preload.
    
    So this changes the definition of the CALGN() macro to target the
    destination pointer instead, and turns it on for Feroceon processors
    where the gain is very noticeable.

    Replace BKL with superblock lock in fat/msdos/vfat
    
    This replaces the use of the BKL in the FAT family of filesystems with the
    existing superblock lock instead.
    
    The code already appears to do mostly proper locking with its own private
    spinlocks (and mutexes), but while the BKL could possibly have been
    dropped entirely, converting it to use the superblock lock (which is just
    a regular mutex) is the conservative thing to do.
    
    As a per-filesystem mutex, it not only won't have any of the possible
    latency issues related to the BKL, but the lock is obviously private to
    the particular filesystem instance and will thus not cause problems for
    entirely unrelated users like the BKL can.

    Remove the lock_kernel() call from chrdev_open()
    
    All in-kernel char device open() functions now either have their own
    lock_kernel() calls or clearly do not need one.

    Add a bunch of cycle_kernel_lock() calls
    
    All of the open() functions which don't need the BKL on their face may
    still depend on its acquisition to serialize opens against driver
    initialization.  So make those functions acquire then release the BKL to be
    on the safe side.

    Add cycle_kernel_lock()
    
    A number of driver functions are so obviously trivial that they do not need
    the big kernel lock - at least not overtly.  It turns out that the
    acquisition of the BKL in driver open() functions can perform a sort of
    poor-hacker's serialization function, delaying the open operation until the
    driver is certain to have completed its initialization.  Add a simple
    cycle_kernel_lock() function for these cases to make it clear that there is
    no need to *hold* the BKL, just to be sure that we can acquire it.

    softirq: remove irqs_disabled warning from local_bh_enable
    
    There's no need to use local_irq_save() over local_irq_disable() in the
    local_bh_enable code since it is a bug to call it with irqs disabled and
    do_softirq will enable irqs if there is any pending work.
    
    Consolidate the code from local_bh_enable and ..._ip to avoid having a
    disconnect between them in the warnings they trigger that is currently
    there.
    
    Also always trigger the warning on in_irq(), not just in the
    trace-irqflags case.

    I dunno. Here's a untested (!!) patch that turns constant-bit
    set/clear_bit ops into byte mask ops (lock orb/andb).
    
    It's not exactly pretty. The reason for using the byte versions is that a
    locked op is serialized in the memory pipeline anyway, so there are no
    forwarding issues (that could slow down things when we access things with
    different sizes), and the byte ops are a lot smaller than 32-bit and
    particularly 64-bit ops (big constants, and the 64-bit ops need the REX
    prefix byte too).
    
    [ Side note: I wonder if we should turn the "test_bit()" C version into a
      "char *" version too.. It could actually help with alias analysis, since
      char pointers can alias anything. So it might be the RightThing(tm) to
      do for multiple reasons. I dunno. It's a separate issue. ]
    
    It does actually shrink the kernel image a bit (a couple of hundred bytes
    on the text segment for my everything-compiled-in image), and while it's
    totally untested the (admittedly few) code generation points I looked at
    seemed sane. And "lock orb" should be noticeably faster than "lock bts".
    
    If somebody wants to play with it, go wild. I didn't do "change_bit()",
    because nobody sane uses that thing anyway. I guarantee nothing. And if it
    breaks, nobody saw me do anything.  You can't prove this email wasn't sent
    by somebody who is good at forging smtp.
    
    This does require a gcc that is recent enough for "__builtin_constant_p()"
    to work in an inline function, but I suspect our kernel requirements are
    already higher than that. And if you do have an old gcc that is supported,
    the worst that would happen is that the optimization doesn't trigger.

    rcu: make rcutorture more vicious: reinstate boot-time testing
    
    This patch re-institutes the ability to build rcutorture directly into
    the Linux kernel.  The reason that this capability was removed was that
    this could result in your kernel being pretty much useless, as rcutorture
    would be running starting from early boot.  This problem has been avoided
    by (1) making rcutorture run only three seconds of every six by default,
    (2) adding a CONFIG_RCU_TORTURE_TEST_RUNNABLE that permits rcutorture
    to be quiesced at boot time, and (3) adding a sysctl in /proc named
    /proc/sys/kernel/rcutorture_runnable that permits rcutorture to be
    quiesced and unquiesced when built into the kernel.
    
    Please note that this /proc file is -not- available when rcutorture
    is built as a module.  Please also note that to get the earlier
    take-no-prisoners behavior, you must use the boot command line to set
    rcutorture's "stutter" parameter to zero.
    
    The rcutorture quiescing mechanism is currently quite crude: loops
    in each rcutorture process that poll a global variable once per tick.
    Suggestions for improvement are welcome.  The default action will
    be to reduce the polling rate to a few times per second.

    rcu: make rcutorture more vicious: add stutter feature
    
    This patch takes a step towards making rcutorture more brutal by allowing
    the test to be automatically periodically paused, with the default being
    to run the test for five seconds then pause for five seconds and repeat.
    This behavior can be controlled using a new "stutter" module parameter, so
    that "stutter=0" gives the old default behavior of running continuously.
    
    Starting and stopping rcutorture more heavily stresses RCU's interaction
    with the scheduler, as well as exercising more paths through the
    grace-period detection code.
    
    Note that the default to "shuffle_interval" has also been adjusted from
    5 seconds to 3 seconds to provide varying overlap with the "stutter"
    interval.
    
    I am still unable to provoke the failures that Alexey has been seeing,
    even with this patch, but will be doing a few additional things to beef
    up rcutorture.

    sched: rework of "prioritize non-migratable tasks over migratable ones"
    
    regarding this commit: 45c01e824991b2dd0a332e19efc4901acb31209f
    
    I think we can do it simpler. Please take a look at the patch below.
    
    Instead of having 2 separate arrays (which is + ~800 bytes on x86_32 and
    twice so on x86_64), let's add "exclusive" (the ones that are bound to
    this CPU) tasks to the head of the queue and "shared" ones -- to the
    end.
    
    In case of a few newly woken up "exclusive" tasks, they are 'stacked'
    (not queued as now), meaning that a task {i+1} is being placed in front
    of the previously woken up task {i}. But I don't think that this
    behavior may cause any realistic problems.
    
    There are a couple of changes on top of this one.
    
    (1) in check_preempt_curr_rt()
    
    I don't think there is a need for the "pick_next_rt_entity(rq, &rq->rt)
    != &rq->curr->rt" check.
    
    enqueue_task_rt(p) and check_preempt_curr_rt() are always called one
    after another with rq->lock being held so the following check
    "p->rt.nr_cpus_allowed == 1 && rq->curr->rt.nr_cpus_allowed != 1" should
    be enough (well, just its left part) to guarantee that 'p' has been
    queued in front of the 'curr'.
    
    (2) in set_cpus_allowed_rt()
    
    I don't thinks there is a need for requeue_task_rt() here.
    
    Perhaps, the only case when 'requeue' (+ reschedule) might be useful is
    as follows:
    
    i) weight == 1 && cpu_isset(task_cpu(p), *new_mask)
    
    i.e. a task is being bound to this CPU);
    
    ii) 'p' != rq->curr
    
    but here, 'p' has already been on this CPU for a while and was not
    migrated. i.e. it's possible that 'rq->curr' would not have high chances
    to be migrated right at this particular moment (although, has chance in
    a bit longer term), should we allow it to be preempted.
    
    Anyway, I think we should not perhaps make it more complex trying to
    address some rare corner cases. For instance, that's why a single queue
    approach would be preferable. Unless I'm missing something obvious, this
    approach gives us similar functionality at lower cost.
    
    Verified only compilation-wise.

    x86: correctly report NR_BANKS in mce_64.c
    
    attached is a no-brainer that makes kernel correctly report
    NR_BANKS for MCE. We are right now limited to NR_BANKS==6, but the
    error message will use the available number of banks instead of the
    defined maximum.
    
    For a Nehalem based system it will print:
    
    "MCE: warning: using only 9 banks"
    
    while the correct message would be
    
    "MCE: warning: using only 6 banks"

    powerpc/4xx: Workaround for PPC440EPx/GRx PCI_28 Errata
    
    The 440EPx/GRx chips don't support PCI MRM commands.  Drivers determine this
    by looking for a zero value in the PCI cache line size register.  However,
    some drivers write to this register upon initialization.  This can cause
    MRMs to be used on these chips, which may cause deadlocks on PLB4.
    
    The workaround implemented here introduces a new indirect_type flag, called
    PPC_INDIRECT_TYPE_BROKEN_MRM.  This is set in the pci_controller structure in
    the pci fixup function for 4xx PCI bridges by determining if the bridge is
    compatible with 440EPx/GRx.  The flag is checked in the indirect_write_config
    function, and forces any writes to the PCI_CACHE_LINE_SIZE register to be
    zero, which will disable MRMs for these chips.
    
    A similar workaround has been tested by AMCC on various PCI cards, such as
    the Silicon Image ATA card and Intel E1000 GIGE card.  Hangs were seen with
    the Silicon Image card, and MRMs were seen on the bus with a PCI analyzer.
    With the workaround in place, the card functioned properly and only Memory
    Reads were seen on the bus with the analyzer.

    x86: fix bug in arch/i386/lib/delay.c file, delay_loop function
    
    when trying to understand how Bogomips are implemented I have found a
    bug in arch/i386/lib/delay.c file, delay_loop function.
    
    The function fails for loops > 2^31+1. It because SF is set when dec
    returns numbers > 2^31.
    
    The fix is to use jnz instruction instead of jns (and add one decl
    instruction to the end to have exactly the same number of loops as in
    original version).
    
    Martin Mares observed:
    
    > It is a long time since I have hacked that file, but you should definitely
    > make sure that the function is never called with a zero argument. In such
    > case, the original version made just a single pass, but your version
    > makes 2^32 of them.
    
    fixed that.

    x86/PCI: fixup early quirk probing
    
    On x86, we do early PCI probing to apply some quirks for chipset bugs.
    However, in a recent cleanup (7bcbc78dea92fdf0947fa48e248da3c993a5690f) a
    thinko was introduced that causes us to probe all subfunctions of even single
    function devices (a function was factored out of an inner loop and a "break"
    became a "return").  Fix that up by making check_dev_quirk() return a value so
    we can keep the factored code intact.

    On OpenMoko soc-audio resume is taking 700ms of the whole resume time of
    1.3s, dominated by writes to the codec over I2C.  This patch shunts the
    resume guts into a workqueue which then is done asynchronously.

    Revert "prohibit rcutorture from being compiled into the kernel"
    
    This reverts commit 9aaffc898ff4a3df18c5fc4b9e0fa47e779ad726.
    
    That commit was a very bad idea. RCU_TORTURE found many boot timing
    bugs and other sorts of bugs in the past, so excluding it from
    boot images is very silly.
    
    The option already depends on DEBUG_KERNEL and is disabled by default.
    Even when it runs, the test threads are reniced. If it annoys people
    we could add a runtime sysctl.

    ftrace: fix "notrace" filtering priority
    
    This is a fix to give notrace filter rules priority over "set_ftrace_filter"
    rules.
    
    This fix ensures that functions which are set to be filtered and are
    concurrently marked as "notrace" don't get recorded. As of now, if
    a record is marked as FTRACE_FL_FILTER and is enabled, then the notrace
    flag is not checked. Tested on x86-32.

    ALSA: hda - Fix bdl_pos_adj value for ATI SB chipsets
    
    ATI SB controllers seem to report the DMA ahead in the amount of FIFO.
    Thus bdl_pos_adj should be 32 for them as default.
    
    Also, the default value is set to -1, which means to make the driver
    to choose the appropriate value.

    ALSA: hda - remove position_fix=3
    
    position_fix=3 is the option to correct the DMA position with the
    FIFO size.  But, it never worked correctly, and we have now more other
    workarounds for the DMA position fixes.  Thus better to remove it.
    
    Also, change POS_FIX_NONE to POS_FIX_LPIB to represent its real role
    better.

    ALSA: hda - Add bdl_pos_adj option
    
    Added a new option, bdl_pos_adj, to adjust the delay of IRQ-wakeup
    timing.
    
    Most HD-audio hardwares have a problem that a BDL IRQ is issued before
    actually the data and the DMA pointer are updated.
    We have already a mechanism to force to delay snd_pcm_period_elapsed()
    calls via workq, but this costs much CPU, and typically the delay is
    within one sample.  Thus, it's more clever to adjust the BDL entries
    instead.
    
    The new option adds the size of the delay in frames.  As default,
    it's set to 1 -- that is, one sample delay.  Even the hardware is
    really correct, one sample delay is relatively harmless in comparison
    with reporting wrong positions.

    cpu topology: always define CPU topology information
    
    This can result in an empty topology directory in sysfs, and requires
    in-kernel users to protect all uses with #ifdef - see
    <http://marc.info/?l=linux-netdev&m=120639033904472&w=2>.
    
    The documentation of CPU topology specifies what the defaults should be if
    only partial information is available from the hardware.  So we can
    provide these defaults as a fallback.
    
    This patch:
    
    - Adds default definitions of the 4 topology macros to <linux/topology.h>
    - Changes drivers/base/topology.c to use the topology macros unconditionally
      and to cope with definitions that aren't lvalues
    - Updates documentation accordingly

    Suspend-related patches for 2.6.27
    
    ACPI PM: Add possibility to change suspend sequence
    
    There are some systems out there that don't work correctly with
    our current suspend/hibernation code ordering.  Provide a workaround
    for these systems allowing them to pass 'acpi_sleep=old_ordering' in
    the kernel command line so that it will use the pre-ACPI 2.0 ("old")
    suspend code ordering.
    
    Unfortunately, this requires us to add a platform hook to the
    resuming of devices for recovering the platform in case one of the
    device drivers' .suspend() routines returns error code.  Namely,
    ACPI 1.0 specifies that _PTS should be called before suspending
    devices, but _WAK still should be called before resuming them in
    order to undo the changes made by _PTS.  However, if there is an
    error during suspending devices, they are automatically resumed
    without returning control to the PM core, so the _WAK has to be
    called from within device_resume() in that cases.
    
    The patch also reorders and refactors the ACPI suspend/hibernation
    code to avoid duplication as far as reasonably possible.

    x86: fix Xorg crash with xf86MapVidMem error
    
    Clarify the usage of mtrr_lookup() in PAT code, and to make PAT code
    resilient to mtrr lookup problems.
    
    Specifically, pat_x_mtrr_type() is restructured to highlight, under what
    conditions we look for mtrr hint. pat_x_mtrr_type() uses a default type
    when there are any errors in mtrr lookup (still maintaining the pat
    consistency). And, reserve_memtype() highlights its usage ot mtrr_lookup
    for request type of '-1' and also defaults in a sane way on any mtrr
    lookup failure.
    
    pat.c looks at mtrr type of a range to get a hint on what mapping type
    to request when user/API: (1) hasn't specified any type (/dev/mem
    mapping) and we do not want to take performance hit by always mapping
    UC_MINUS. This will be the case for /dev/mem mappings used to map BIOS
    area or ACPI region which are WB'able. In this case, as long as MTRR is
    not WB, PAT will request UC_MINUS for such mappings.
    
    (2) user/API requests WB mapping while in reality MTRR may have UC or
    WC. In this case, PAT can map as WB (without checking MTRR) and still
    effective type will be UC or WC. But, a subsequent request to map same
    region as UC or WC may fail, as the region will get trackked as WB in
    PAT list. Looking at MTRR hint helps us to track based on effective type
    rather than what user requested. Again, here mtrr_lookup is only used as
    hint and we fallback to WB mapping (as requested by user) as default.
    
    In both cases, after using the mtrr hint, we still go through the
    memtype list to make sure there are no inconsistencies among multiple
    users.

    Get rid of a superfluous acpi_pm_device_sleep_state() parameter.  The
    only legitimate value of that parameter must be derived from the first
    parameter, which is what all the callers already do.  (However, this
    does not address the fact that ACPI still doesn't set up those flags.)

    This patch add a check to the PPC4xx PCIe driver to detect if the port

    board which has an option to either select 2 PCIe ports or 1 PCIe port
    and one SATA port. The SATA port and the 1st PCIe port pins are multiplexed
    so we can't start both drivers.

    PCI: introduce pci_slot
    
    Currently, /sys/bus/pci/slots/ only exposes hotplug attributes when a
    hotplug driver is loaded, but PCI slots have attributes such as address,
    speed, width, etc.  that are not related to hotplug at all.
    
    Introduce pci_slot as the primary data structure and kobject model.
    Hotplug attributes described in hotplug_slot become a secondary
    structure associated with the pci_slot.
    
    This patch only creates the infrastructure that allows the separation of
    PCI slot attributes and hotplug attributes.  In this patch, the PCI
    hotplug core remains the only user of this infrastructure, and thus,
    /sys/bus/pci/slots/ will still only become populated when a hotplug
    driver is loaded.
    
    A later patch in this series will add a second user of this new
    infrastructure and demonstrate splitting the task of exposing pci_slot
    attributes from hotplug_slot attributes.
    
      - Make pci_slot the primary sysfs entity. hotplug_slot becomes a
        subsidiary structure.
        o pci_create_slot() creates and registers a slot with the PCI core
        o pci_slot_add_hotplug() gives it hotplug capability
    
      - Change the prototype of pci_hp_register() to take the bus and
        slot number (on parent bus) as parameters.
    
      - Remove all the ->get_address methods since this functionality is
        now handled by pci_slot directly.

    shpchp: check firmware before taking control
    
    Fix the following problems of shpchp driver about getting hotplug
    control from firmware.
    
      - The shpchp driver must not control the hotplug controller if it
        fails to get control from the firmware. But current shpchp
        controls the hotplug controller regardless the result, because it
        doesn't check the return value of get_hp_hw_control_from_firmware().
    
      - Current shpchp driver doesn't support _OSC.
    
    The pciehp driver already have the code for evaluating _OSC and OSHP
    and shpchp and pciehp can share it. So this patch move that code from
    pciehp to acpi_pcihp.c.

commit 1eede070a59e1cc73da51e1aaa00d9ab86572cfc
Author: Rafael J. Wysocki <rjw@sisk.pl>
Date:   Tue May 20 23:00:01 2008 +0200

    Introduce new top level suspend and hibernation callbacks
    
    Introduce 'struct pm_ops' and 'struct pm_ext_ops' ('ext' meaning
    'extended') representing suspend and hibernation operations for bus
    types, device classes, device types and device drivers.
    
    Modify the PM core to use 'struct pm_ops' and 'struct pm_ext_ops'
    objects, if defined, instead of the ->suspend(), ->resume(),
    ->suspend_late(), and ->resume_early() callbacks (the old callbacks
    will be considered as legacy and gradually phased out).
    
    The main purpose of doing this is to separate suspend (aka S2RAM and
    standby) callbacks from hibernation callbacks in such a way that the
    new callbacks won't take arguments and the semantics of each of them
    will be clearly specified.  This has been requested for multiple
    times by many people, including Linus himself, and the reason is that
    within the current scheme if ->resume() is called, for example, it's
    difficult to say why it's been called (ie. is it a resume from RAM or
    from hibernation or a suspend/hibernation failure etc.?).
    
    The second purpose is to make the suspend/hibernation callbacks more
    flexible so that device drivers can handle more than they can within
    the current scheme.  For example, some drivers may need to prevent
    new children of the device from being registered before their
    ->suspend() callbacks are executed or they may want to carry out some
    operations requiring the availability of some other devices, not
    directly bound via the parent-child relationship, in order to prepare
    for the execution of ->suspend(), etc.
    
    Ultimately, we'd like to stop using the freezing of tasks for suspend
    and therefore the drivers' suspend/hibernation code will have to take
    care of the handling of the user space during suspend/hibernation.
    That, in turn, would be difficult within the current scheme, without
    the new ->prepare() and ->complete() callbacks.

    PCI: boot parameter to avoid expansion ROM memory allocation
    
    Contention for scarce PCI memory resources has been growing
    due to an increasing number of PCI slots in large multi-node
    systems.  The kernel currently attempts by default to
    allocate memory for all PCI expansion ROMs so there has
    also been an increasing number of PCI memory allocation
    failures seen on these systems.  This occurs because the
    BIOS either (1) provides insufficient PCI memory resource
    for all the expansion ROMs or (2) provides adequate PCI
    memory resource for expansion ROMs but provides the
    space in kernel unexpected BIOS assigned P2P non-prefetch
    windows.
    
    The resulting PCI memory allocation failures may be benign
    when related to memory requests for expansion ROMs themselves
    but in some cases they can occur when attempting to allocate
    space for more critical BARs.  This can happen when a successful
    expansion ROM allocation request consumes memory resource
    that was intended for a non-ROM BAR.  We have seen this
    happen during PCI hotplug of an adapter that contains a
    P2P bridge where successful memory allocation for an
    expansion ROM BAR on device behind the bridge consumed
    memory that was intended for a non-ROM BAR on the P2P bridge.
    In all cases the allocation failure messages can be very
    confusing for users.
    
    This patch provides a new 'pci=norom' kernel boot parameter
    that can be used to disable the default PCI expansion ROM memory
    resource allocation.  This provides a way to avoid the above
    described issues on systems that do not contain PCI devices
    for which drivers or user-level applications depend on the
    default PCI expansion ROM memory resource allocation behavior.

    PCI: Disable PME during PCI scan
    
    If a device supports #PME and can generate PME events from D0, we may see
    superfluous events before a driver is loaded (drivers should only enable PME as
    needed), preventing suspend from working if the corresponding GPE was enabled.
    
    Likewise, if the ACPI device has the _PRW object, the _PSW/_DSW object will be
    called in order to disable the wakeup functionality. But when it is allowed to
    wake up the sleeping state, OSPM will enable it again.
    
    So we should disable PME in the course of scanning PCI devices and enable it
    again only when PME events are actually required to be generated from the
    requested PCI state (for example, D3_hot or D3_cold).  It is also safe to
    disable PME again when the PME is disabled for the PCI devices.

    This is very trivial patch. We're transitioning to the cpm_muram_*

    Less trivial changes:
    - BD_SC_* defines were defined in the cpm.h and qe.h, so to avoid redefines
      we remove BD_SC from the qe.h and use cpm.h along with cpm_muram_*
      prototypes;
    - qe_muram_dump was unused and thus removed;
    - added some code to the cpm_common.c to support legacy QE bindings
      (data-only node name).
    - For convenience, define qe_* calls to cpm_*. So drivers need not to be
      changed.

    powerpc/QE: add support for QE USB clocks routing
    
    This patch adds a function to the qe_lib to setup QE USB clocks routing.
    To setup clocks safely, cmxgcr register needs locking, so I just reused

    The idea behind placing clocks routing functions into the qe_lib is that
    later we'll hopefully switch to the generic Linux Clock API, thus, for
    example, FHCI driver may be used for QE and CPM chips without nasty #ifdefs.

    ftrace: disable tracing when current_tracer is set to "none"
    
    Found that inspite of setting the current_tracer to "none", trace from
    the previous trace type continued to be collected. The patch below fixes
    this and causes the trace to be disabled when the "none" type is
    selected.
    
    Compile and boot tested the patch for functionality.

    x86: set PAE PHYSICAL_MASK_SHIFT to 44 bits.
    
    When a 64-bit x86 processor runs in 32-bit PAE mode, a pte can
    potentially have the same number of physical address bits as the
    64-bit host ("Enhanced Legacy PAE Paging").  This means, in theory,
    we could have up to 52 bits of physical address in a pte.
    
    The 32-bit kernel uses a 32-bit unsigned long to represent a pfn.
    This means that it can only represent physical addresses up to 32+12=44
    bits wide.  Rather than widening pfns everywhere, just set 2^44 as the
    Linux x86_32-PAE architectural limit for physical address size.

    mm, x86: shrink_active_range() should check all
    
    Now we are using register_e820_active_regions() instead of

    So we need to make shrink_active_range() smarter.
    
    shrink_active_range() is a generic MM function in mm/page_alloc.c but
    it is only used on 32-bit x86. Should we move it back to some file in

    powerpc: Improve (in|out)_[bl]eXX() asm code
    
    Since commit 4cb3cee03d558fd457cb58f56c80a2a09a66110c the code generated
    for the in_beXX() and out_beXX() mmio functions has been sub-optimal.
    
    The out_leXX() family of functions are created with the macro
    DEF_MMIO_OUT_LE() while the out_beXX() family are created with
    DEF_MMIO_OUT_BE().  In what was perhaps a bit too much macro use, both of
    these macros are in turn created via the macro DEF_MMIO_OUT().
    
    For the LE versions, eventually they boil down to an asm that will look
    something like this:
    asm("sync; stwbrx %1,0,%2" : "=m" (*addr) : "r" (val), "r" (addr));
    
    The issue is that the "stwbrx" instruction only comes in an indexed, or
    'x', version, in which the address is represented by the sum of two
    registers (the "0,%2").  Unfortunately, gcc doesn't have a constraint for
    an indexed memory reference.  The "m" constraint allows both indexed and
    offset, i.e. register plus constant, memory references and there is no
    "stwbr" version for offset references.  "m" also allows updating addresses
    and there is no 'u' version of "stwbrx" like there is with "stwux".
    
    The unused first operand to the asm is just to tell gcc that *addr is an
    output of the asm.  The address used is passed in a single register via the
    third asm operand, and the index register is just hard coded as 0.  This
    means gcc is forced to put the address in a single register and can't use
    index addressing, e.g. if one has the data in register 9, a base address in
    register 3 and an index in register 4, gcc must emit code like "add 11,4,3;
    stwbrx 9,0,11" instead of just "stwbrx 9,4,3".  This costs an extra add
    instruction and another register.
    
    For gcc 4.0 and older, there doesn't appear to be anything that can be
    done.  But for 4.1 and newer, there is a 'Z' constraint.  It does not allow
    "updating" addresses, but does allow both indexed and offset addresses.
    However, the only allowed constant offset is 0.  We can then use the
    undocumented 'y' operand modifier, which causes gcc to convert "0(reg)"
    into the equivilient "0,reg" format that can be used with stwbrx.
    
    This brings us the to problem with the BE version.  In this case, the "stw"
    instruction does have both indexed and non-indexed versions.  The final asm
    ends up looking like this:
    asm("sync; stw%U0%X0 %1,%0" : "=m" (*addr) : "r" (val), "r" (addr));
    
    The undocumented codes "%U0" and "%0X" will generate a 'u' if the memory
    reference should be an auto-updating one, and an 'x' if the memory
    reference is indexed, respectively.  The third operand is unused, it's just
    there because asm the code is reused from the LE version.  However, gcc
    does not know this, and generates unnecessary code to stick addr in a
    register!  To use the example from the LE version, gcc will generate "add
    11,4,3; stwx 9,4,3".  It is able to use the indexed address "4,3" for the
    "stwx", but still thinks it needs to put 4+3 into register 11, which will
    never be used.
    
    This also ends up happening a lot for the offset addressing mode, where
    common code like this:  out_be32(&device_registers->some_register, data);
    uses an instruction like "stw 9, 42(3)", where register 3 has the pointer
    device_registers and 42 is the offset of some_register in that structure.
    gcc will be forced to generate the unnecessary instruction "addi 11, 3, 42"
    to put the address into a single (unused) register.
    
    The in_* versions end up having these exact same problems as well.

    powerpc: Fix irq_alloc_host() reference counting and callers
    
    When I changed irq_alloc_host() to take an of_node
    (52964f87c64e6c6ea671b5bf3030fb1494090a48: "Add an optional
    device_node pointer to the irq_host"), I botched the reference
    counting semantics.
    
    Stephen pointed out that it's irq_alloc_host()'s business if
    it needs to take an additional reference to the device_node,
    the caller shouldn't need to care.

    sched: CPU hotplug events must not destroy scheduler domains created by the cpusets
    
    First issue is not related to the cpusets. We're simply leaking doms_cur.
    It's allocated in arch_init_sched_domains() which is called for every
    hotplug event. So we just keep reallocation doms_cur without freeing it.
    I introduced free_sched_domains() function that cleans things up.
    
    Second issue is that sched domains created by the cpusets are
    completely destroyed by the CPU hotplug events. For all CPU hotplug
    events scheduler attaches all CPUs to the NULL domain and then puts
    them all into the single domain thereby destroying domains created
    by the cpusets (partition_sched_domains).
    The solution is simple, when cpusets are enabled scheduler should not
    create default domain and instead let cpusets do that. Which is
    exactly what the patch does.

    sched: fix cpupri hotplug support
    
    The RT folks over at RedHat found an issue w.r.t. hotplug support which
    was traced to problems with the cpupri infrastructure in the scheduler:
    
    https://bugzilla.redhat.com/show_bug.cgi?id=449676
    
    This bug affects 23-rt12+, 24-rtX, 25-rtX, and sched-devel.  This patch
    applies to 25.4-rt4, though it should trivially apply to most cpupri enabled
    kernels mentioned above.
    
    It turned out that the issue was that offline cpus could get inadvertently
    registered with cpupri so that they were erroneously selected during
    migration decisions.  The end result would be an OOPS as the offline cpu
    had tasks routed to it.
    
    This patch generalizes the old join/leave domain interface into an
    online/offline interface, and adjusts the root-domain/hotplug code to
    utilize it.
    
    I was able to easily reproduce the issue prior to this patch, and am no
    longer able to reproduce it after this patch.  I can offline cpus
    indefinately and everything seems to be in working order.
    
    Thanks to Arnaldo (acme), Thomas, and Peter for doing the legwork to point
    me in the right direction.  Also thank you to Peter for reviewing the
    early iterations of this patch.

    sched: print module list in the "scheduling while atomic" warning
    
    For the normal WARN_ON() etc we added a print-the-modules-list already,
    which is very useful to figure out candidates for certain types of bugs.
    
    This patch adds the same print to the "scheduling while atomic" BUG warning,
    for the same reason: when we get here it's very useful to see which modules
    are loaded, to narrow down the candidate code list.

    sched: prioritize non-migratable tasks over migratable ones
    
    Dmitry Adamushko pointed out a known flaw in the rt-balancing algorithm
    that could allow suboptimal balancing if a non-migratable task gets
    queued behind a running migratable one.  It is discussed in this thread:
    
    http://lkml.org/lkml/2008/4/22/296
    
    This issue has been further exacerbated by a recent checkin to
    sched-devel (git-id 5eee63a5ebc19a870ac40055c0be49457f3a89a3).
    
    >From a pure priority standpoint, the run-queue is doing the "right"
    thing. Using Dmitry's nomenclature, if T0 is on cpu1 first, and T1
    wakes up at equal or lower priority (affined only to cpu1) later, it
    *should* wait for T0 to finish.  However, in reality that is likely
    suboptimal from a system perspective if there are other cores that
    could allow T0 and T1 to run concurrently.  Since T1 can not migrate,
    the only choice for higher concurrency is to try to move T0.  This is
    not something we addessed in the recent rt-balancing re-work.
    
    This patch tries to enhance the balancing algorithm by accomodating this
    scenario.  It accomplishes this by incorporating the migratability of a
    task into its priority calculation.  Within a numerical tsk->prio, a
    non-migratable task is logically higher than a migratable one.  We
    maintain this by introducing a new per-priority queue (xqueue, or
    exclusive-queue) for holding non-migratable tasks.  The scheduler will
    draw from the xqueue over the standard shared-queue (squeue) when
    available.
    
    There are several details for utilizing this properly.
    
    1) During task-wake-up, we not only need to check if the priority
       preempts the current task, but we also need to check for this
       non-migratable condition.  Therefore, if a non-migratable task wakes
       up and sees an equal priority migratable task already running, it
       will attempt to preempt it *if* there is a likelyhood that the
       current task will find an immediate home.
    
    2) Tasks only get this non-migratable "priority boost" on wake-up.  Any
       requeuing will result in the non-migratable task being queued to the
       end of the shared queue.  This is an attempt to prevent the system
       from being completely unfair to migratable tasks during things like
       SCHED_RR timeslicing.
    
    I am sure this patch introduces potentially "odd" behavior if you
    concoct a scenario where a bunch of non-migratable threads could starve
    migratable ones given the right pattern.  I am not yet convinced that
    this is a problem since we are talking about tasks of equal RT priority
    anyway, and there never is much in the way of guarantees against
    starvation under that scenario anyway. (e.g. you could come up with a
    similar scenario with a specific timing environment verses an affinity
    environment).  I can be convinced otherwise, but for now I think this is
    "ok".

    [SCSI] zfcp: Fix mempool pointer for GID_PN request allocation
    
    When allocating memory for GID_PN nameserver requests, the allocation
    function stores the pointer to the mempool, but then overwrites the
    pointer via memset. Later, the wrong function to free the memory will
    be called, since this is based on the stored pointer.
    
    Fix this by first initializing the struct and then storing the pointer.

    [SCSI] zfcp: receiving an unsolicted status can lead to I/O stall
    
    Processing of an unsolicted status request can lead to a locking race
    of the request_queue's queue_lock during the recreation of the
    used up status read request while still in interrupt context
    of the response handler.
    
    Detaching the 'refill' of the long running status read requests from
    the handler to a scheduled work is solving this issue.
    
    In addition, each refill-run is trying to re-establish the full amount
    of status read requests, which might have failed in earlier runs.

    [SCSI] zfcp: sysfs attributes for fabric and channel latencies
    
    The latency information is provided on a SCSI device level (LUN)
    which can be found at the following location
    
     /sys/class/scsi_device/<H:C:T:L>/device/cmd_latency
     /sys/class/scsi_device/<H:C:T:L>/device/read_latency
     /sys/class/scsi_device/<H:C:T:L>/device/write_latency
    
    Each sysfs attribute provides the available data: min, max and sum for
    fabric and channel latency and the number of requests processed.
    
    An overrun of the variables is neither detected nor treated.  The file
    has to be read twice to make a meaningful statement, because only the
    differences of the values between the two reads can be used.  A reset
    of the values can be achieved by writing to the attribute.

    [SCSI] scsi_dh: Add a single threaded workqueue for initializing paths
    
    Before this patch set (SCSI hardware handlers), initialization of a
    path was done asynchronously. Doing that requires a workqueue in each
    device/hardware handler module and leads to unneccessary complication
    in the device handler code, making it difficult to read the code and
    follow the state diagram.
    
    Moving that workqueue to this level makes the device handler code simpler.
    Hence, the workqueue is moved to dm level.
    
    A new workqueue is added instead of adding it to the existing workqueue
    (kmpathd) for the following reasons:
    	1. Device activation has to happen faster, stacking them along
    	   with the other workqueue might lead to unnecessary delay
    	   in the activation of the path.
    	2. The effect could be felt the other way too. i.e the current
    	   events that are handled by the existing workqueue might get
    	   a delayed response.

    [SCSI] scsi_dh: Use SCSI device handler in dm-multipath
    
    This patch converts dm-mpath to use scsi device handlers instead of
    dm's hardware handlers.
    
    This patch does not add any new functionality. Old behaviors remain and
    userspace tools work as is except that arguments supplied with hardware
    handler are ignored.
    
    One behavioral exception is: Activation of a path is synchronous in this
    patch, opposed to the older behavior of being asynchronous (changed in
    patch 07: scsi_dh: Add a single threaded workqueue for initializing a path)
    
    Note: There is no need to get a reference for the device handler module
    (as it was done in the dm hardware handler case) here as the reference
    is held when the device was first found. Instead we check and make sure
    that support for the specified device is present at table load time.

    [SCSI] scsi_dh: add infrastructure for SCSI Device Handlers
    
    Some of the storage devices (that can be accessed through multiple paths),
    do need some special handling for
    	1. Activating the passive path of the storage access.
    	2. Decode and handle the special sense codes returned by the devices.
    	3. Handle the I/Os being sent to the passive path, especially
               during the device probe time.
    when accessed through multiple paths.
    
    As of today this special device handling is done at the dm-multipath
    layer using dm-handlers. That works well for (1); for (2) to be handled
    at dm layer, scsi sense information need to be exported from SCSI to dm-layer,
    which is not very attractive; (3) cannot be done at all at the dm layer.
    
    Device handler has been moved to SCSI mainly to handle (2) and (3) properly.

    x86: reserve highmem pages via reserve_early
    
    This patch makes early reserved highmem pages become reserved
    pages. This can be used for highmem pages allocated by bootloader such
    as EFI memory map, linked list of setup_data, etc.

    aperture_64.c: duplicated code, buggy?
    
    Hi!
    
    void __init early_gart_iommu_check(void)
    
    contains
    
    	for (num = 24; num < 32; num++) {
    		if (!early_is_k8_nb(read_pci_config(0, num, 3, 0x00)))
    			continue;
    
    loop, with very similar loop duplicated in
    
    void __init gart_iommu_hole_init(void)
    
    . First copy of a loop seems to be buggy, too. It uses 0 as a "nothing
    set" value, which may actually bite us in last_aper_enabled case
    (because it may be often zero).
    
    (Beware, it is hard to test this patch, because this code has about
    2^8 different code paths, depending on hardware and cmdline settings).
    
    Plus, the second loop does not check for consistency of
    aper_enabled. Should it?

    [POWERPC] fsl: Update fsl_soc to use cell-index property of I2C nodes
    
    Currently, fsl_i2c_of_init() uses the order of the I2C adapter nodes in the
    device tree to enumerate the I2C adapters.  Instead, let's check for the
    cell-index property and use it if it exists.
    
    This is handy for device drivers that need to identify the I2C adapters by
    specific numbers.  The Freescale MPC8610 ASoC V2 sound drivers are an example.

    For debug level add CSRR0/1 and SRR0/1.
    For machine check level add DSRR0/1, CSRR0/1, and SRR0/1.
    
    On FSL Book-E parts we always save/restore the MAS registers for critical,

    the MMUCR.
    
    Additionally, we save and restore the ksp_limit since we have to adjust it

    The i2c_devices[] array in fsl_soc.c lists all the I2C nodes that are supported
    on Freescale boards.  Add an entry for the Cirrus Logic CS4270 so that a
    new-style CS4270 driver will work.

    [POWERPC] fsl: PCIe MSI support for 83xx/85xx/86xx processors.
    
    This MSI driver can be used on 83xx/85xx/86xx board.
    In this driver, virtual interrupt host and chip were
    setup. There are 256 MSI interrupts in this host, Every 32
    MSI interrupts cascaded to one IPIC/MPIC interrupt.
    The chip was treated as edge sensitive and some necessary
    functions were setup for this chip.
    
    Before using the MSI interrupt, PCI/PCIE device need to
    ask for a MSI interrupt in the 256 MSI interrupts. A 256bit
    bitmap show which MSI interrupt was used, reserve bit in
    the bitmap can be used to force the device use some designate
    MSI interrupt in the 256 MSI interrupts. Sometimes this is useful
    for testing the all the MSI interrupts. The msi-available-ranges
    property in the dts file was used for this purpose.

    If we're using vcpu_info mapping, then make sure its restored on all
    processors before relasing them from stop_machine.
    
    The only complication is that if this fails, we can't continue because
    we've already made assumptions that the mapping is available (baked in
    calls to the _direct versions of the functions, for example).
    
    Fortunately this can only happen with a 32-bit hypervisor, which may
    possibly run out of mapping space.  On a 64-bit hypervisor, this is a
    non-issue.

    xen: avoid hypercalls when updating unpinned pud/pmd
    
    When operating on an unpinned pagetable (ie, one under construction or
    destruction), it isn't necessary to use a hypercall to update a
    pud/pmd entry.  Jan Beulich observed that a similar optimisation
    avoided many thousands of hypercalls while doing a kernel build.
    
    One tricky part is that early in the kernel boot there's no page
    structure, so we can't check to see if the page is pinned.  In that
    case, we just always use the hypercall.

    ftrace: user update and disable dynamic ftrace daemon
    
    In dynamic ftrace, the mcount function starts off pointing to a stub
    function that just returns.
    
    On start up, the call to the stub is modified to point to a "record_ip"
    function. The job of the record_ip function is to add the function to
    a pre-allocated hash list. If the function is already there, it simply is
    ignored, otherwise it is added to the list.
    
    Later, a ftraced daemon wakes up and calls kstop_machine if any functions
    have been recorded, and changes the calls to the recorded functions to
    a simple nop.  If no functions were recorded, the daemon goes back to sleep.
    
    The daemon wakes up once a second to see if it needs to update any newly
    recorded functions into nops.  Usually it does not, but if a lot of code
    has been executed for the first time in the kernel, the ftraced daemon
    will call kstop_machine to update those into nops.
    
    The problem currently is that there's no way to stop the daemon from doing
    this, and it can cause unneeded latencies (800us which for some is bothersome).
    
    This patch adds a new file /debugfs/tracing/ftraced_enabled. If the daemon
    is active, reading this will return "enabled\n" and "disabled\n" when the
    daemon is not running. To disable the daemon, the user can echo "0" or
    "disable" into this file, and "1" or "enable" to re-enable the daemon.
    
    Since the daemon is used to convert the functions into nops to increase
    the performance of the system, I also added that anytime something is
    written into the ftraced_enabled file, kstop_machine will run if there
    are new functions that have been detected that need to be converted.
    
    This way the user can disable the daemon but still be able to control the
    conversion of the mcount calls to nops by simply,
    
      "echo 0 > /debugfs/tracing/ftraced_enabled"
    
    when they need to do more conversions.
    
    To see the number of converted functions:
    
      "cat /debugfs/tracing/dyn_ftrace_total_info"

    ftrace: distinguish kretprobe'd functions in trace logs
    
    Tracing functions via ftrace which have a kretprobe installed on them, can produce misleading output in their trace logs. E.g, consider the correct trace of the following sequence:
    
    do_IRQ()
    {
    ~
      irq_enter();
    ~
    }
    
    Trace log (sample):
    <idle>-0     [00] 4154504455.781616: irq_enter <- do_IRQ
    
    But if irq_enter() has a kretprobe installed on it, the return value stored on the stack at each invocation is modified to divert the return to a kprobe trampoline function called kretprobe_trampoline(). So with this the trace would (currently) look like:
    
    <idle>-0     [00] 4154504455.781616: irq_enter <- kretprobe_trampoline
    
    Now this is quite misleading to the end user, as it suggests something that didn't actually happen. So just to avoid such misinterpretations, the inlined patch aims to output such a log as:
    
    <idle>-0     [00] 4154504455.781616: irq_enter <- [unknown/kretprobe'd]

    Of course, for non-x86, you kind of have to expect drivers to be
    well-behaved, so non-x86 can probably avoid this simply because there are
    less relevant drivers involved.
    
    Here's a UNTESTED patch for x86 that may or may not compile and work, and
    which serializes (on a compiler level) the IO accesses against regular
    memory accesses.
    
    __read[bwlq]()/__write[bwlq]() are not serialized with a :"memory"
    barrier, although since they still use "asm volatile" I suspect that i
    practice they are probably serial too. Did not look very closely at any
    generated code (only did a trivial test to see that the code looks
    *roughly* correct).

    [POWERPC] Convert remaining dts-v0 files to v1
    
    At the moment we have a mixture of left-over version 0 and new-format
    version 1 files in arch/powerpc/boot/dts.  This is potentially
    confusing to people new to the dts format attempting to figure it out.
    
    So, this patch converts all the as-yet unconverted dts v0 files and
    converts them to v1.  They're mechanically-converted, and not hand
    tweaked so in some cases they're not 100% in keeping with usual v1
    style, but the convertor program does have some heuristics so the
    discrepancies aren't too bad.
    
    I have checked that this patch produces no changes to the resulting
    dtb binaries.

    [POWERPC] Refactor DCR code
    
    Previously, DCR support was configured at compile time to either use
    MMIO or native dcr instructions.  Although this works for most
    platforms, it fails on FPGA platforms:
    
    1) Systems may include more than one DCR bus.
    2) Systems may be native DCR capable and still use memory mapped DCR interface.
    
    This patch provides runtime support based on the device trees for the
    case where CONFIG_PPC_DCR_MMIO and CONFIG_PPC_DCR_NATIVE are both
    selected.  Previously, this was a poorly defined configuration, which
    happened to provide NATIVE support.  The runtime selection is made
    based on the dcr-controller having a 'dcr-access-method' attribute
    in the device tree.  If only one of the above options is selected,
    then the code uses #defines to select only the used code in order to
    avoid introducing overhead in existing usage.

      drivers/built-in.o: In function `xen_suspend':

    |
    |      xen: implement save/restore
    
    the problem is that drivers/xen/manage.c is built unconditionally if
    CONFIG_XEN is enabled and makes use of xen_suspend(), but
    drivers/char/hvc_xen.c, where the xen_suspend() method is implemented,
    is only build if CONFIG_HVC_XEN=y as well.
    
    i have solved this by providing a NOP implementation for xen_suspend()
    in the !CONFIG_HVC_XEN case.

    |   xen: add p2m mfn_list_list
    
    Which is somewhat surprising, as on native hardware Xen client side
    should have little to no side-effects.
    
    After some head scratching, it turns out the following happened:
    randconfig enabled the following Xen options:
    
      CONFIG_XEN=y
      CONFIG_XEN_MAX_DOMAIN_MEMORY=8
      # CONFIG_XEN_BLKDEV_FRONTEND is not set
      # CONFIG_XEN_NETDEV_FRONTEND is not set
      CONFIG_HVC_XEN=y
      # CONFIG_XEN_BALLOON is not set
    
    which activated this piece of code in arch/x86/xen/mmu.c:
    
    > @@ -69,6 +69,13 @@
    >  	__attribute__((section(".data.page_aligned"))) =
    >  		{ [ 0 ... TOP_ENTRIES - 1] = &p2m_missing[0] };
    >

    > +	__attribute__((section(".bss.page_aligned")));
    
    The problem is, you must only put variables into .bss.page_aligned that
    have a _size_ that is _exactly_ page aligned. In this case the size of
    p2m_top_mfn_list is not page aligned:
    
     80b8d000 b p2m_top_mfn

     80b9f008 b bm_pte
    
    So all subsequent variables get unaligned which, depending on luck,
    breaks the kernel in various funny ways. In this case what killed the
    kernel first was the misaligned bootmap pte page, resulting in that
    creative crash above.
    
    Anyway, this was a fun bug to track down :-)
    
    I think the moral is that .bss.page_aligned is a dangerous construct in
    its current form, and the symptoms of breakage are very non-trivial, so
    i think we need build-time checks to make sure all symbols in
    .bss.page_aligned are truly page aligned.
    
    The Xen fix below gets the kernel booting again.

    xen: implement save/restore
    
    This patch implements Xen save/restore and migration.
    
    Saving is triggered via xenbus, which is polled in
    drivers/xen/manage.c.  When a suspend request comes in, the kernel
    prepares itself for saving by:
    
    1 - Freeze all processes.  This is primarily to prevent any
        partially-completed pagetable updates from confusing the suspend
        process.  If CONFIG_PREEMPT isn't defined, then this isn't necessary.
    
    2 - Suspend xenbus and other devices
    
    3 - Stop_machine, to make sure all the other vcpus are quiescent.  The
        Xen tools require the domain to run its save off vcpu0.
    
    4 - Within the stop_machine state, it pins any unpinned pgds (under
        construction or destruction), performs canonicalizes various other
        pieces of state (mostly converting mfns to pfns), and finally
    
    5 - Suspend the domain
    
    Restore reverses the steps used to save the domain, ending when all
    the frozen processes are thawed.

    Add code to:

        In order to deal with that, we always use a copy of the pfn and
        indirect off that all the time.  However, we fall back to using the
        mfn if the pfn hasn't been initialized yet.
    
     2. Restore the console event channel, and rebind it to the existing irq.

    xen: efficiently support a holey p2m table
    
    When using sparsemem and memory hotplug, the kernel's pseudo-physical
    address space can be discontigious.  Previously this was dealt with by
    having the upper parts of the radix tree stubbed off.  Unfortunately,
    this is incompatible with save/restore, which requires a complete p2m
    table.
    
    The solution is to have a special distinguished all-invalid p2m leaf
    page, which we can point all the hole areas at.  This allows the tools
    to see a complete p2m table, but it only costs a page for all memory
    holes.
    
    It also simplifies the code since it removes a few special cases.

    For a 32-bit guest, the default value of 8GB is probably sufficient;
    there's not much point in giving a 32-bit machine much more memory

    setup_early_printk() from successfully enabling the boot console -
    unless you make it a preferred console too...
    
    Also, make xenboot console output distinct from normal console output,
    since it gets repeated when the console handover happens, and the
    duplicated output is confusing without disambiguation.

    xen pvfb: Dynamic mode support (screen resizing)
    
    The pvfb backend indicates dynamic mode support by creating node
    feature_resize with a non-zero value in its xenstore directory.
    xen-fbfront sends a resize notification event on mode change.  Fully
    backwards compatible both ways.
    
    Framebuffer size and initial resolution can be controlled through
    kernel parameter xen_fbfront.video.  The backend enforces a separate
    size limit, which it advertises in node videoram in its xenstore
    directory.
    
    xen-kbdfront gets the maximum screen resolution from nodes width and
    height in the backend's xenstore directory instead of hardcoding it.
    
    Additional goodie: support for larger framebuffers (512M on a 64-bit
    system with 4K pages).
    
    Changing the number of bits per pixels dynamically is not supported,
    yet.

    xen: Enable console tty by default in domU if it's not a dummy
    
    Without console= arguments on the kernel command line, the first
    console to register becomes enabled and the preferred console (the one
    behind /dev/console).  This is normally tty (assuming
    CONFIG_VT_CONSOLE is enabled, which it commonly is).
    
    This is okay as long tty is a useful console.  But unless we have the
    PV framebuffer, and it is enabled for this domain, tty0 in domU is
    merely a dummy.  In that case, we want the preferred console to be the
    Xen console hvc0, and we want it without having to fiddle with the
    kernel command line.  Commit b8c2d3dfbc117dff26058fbac316b8acfc2cb5f7
    did that for us.
    
    Since we now have the PV framebuffer, we want to enable and prefer tty
    again, but only when PVFB is enabled.  But even then we still want to
    enable the Xen console as well.
    
    Problem: when tty registers, we can't yet know whether the PVFB is
    enabled.  By the time we can know (xenstore is up), the console setup
    game is over.
    
    Solution: enable console tty by default, but keep hvc as the preferred
    console.  Change the preferred console to tty when PVFB probes
    successfully, unless we've been given console kernel parameters.

    hrtimer: remove warning in hres_timers_resume
    
    hres_timers_resume() warns if there appears to be more than one cpu
    online.  This warning makes sense when the suspend/resume mechanism
    offlines all cpus but one during the suspend/resume process.
    
    However, Xen suspend does not need to offline the other cpus; it
    merely keeps them tied up in stop_machine() while the virtual machine
    is suspended.  The warning hres_timers_resume issues is therefore
    spurious.

    ftrace: set_ftrace_notrace feature
    
    While debugging latencies in the RT kernel, I found that it would be nice
    to be able to filter away functions from the trace than just to filter
    on functions.
    
    I added a new interface to the debugfs tracing directory called
    
      set_ftrace_notrace
    
    When dynamic frace is enabled, this lets you filter away functions that will
    not be recorded in the trace. It is similar to adding 'notrace' to those
    functions but by doing it without recompiling the kernel.
    
    Here's how set_ftrace_filter and set_ftrace_notrace interact. Remember, if
    set_ftrace_filter is set, it removes all functions from the trace execpt for
    those listed in the set_ftrace_filter. set_ftrace_notrace will prevent those
    functions from being traced.
    
    If you were to set one function in both set_ftrace_filter and
    set_ftrace_notrace and that function was the same, then you would end up
    with an empty trace.
    
    the set of functions to trace is:
    
      set_ftrace_filter == empty then
    
         all functions not in set_ftrace_notrace
    
      else
    
         set of the set_ftrace_filter and not in set of set_ftrace_notrace.

    ftrace: remove printks from irqsoff trace
    
    Printing out new max latencies was fine for the old RT tracer. But for
    mainline it is a bit messy. We also need to test if the run queue
    is locked before we can do the print. This means that we may not be
    printing out latencies if the run queue is locked on another CPU.
    This produces inconsistencies in the output.
    
    This patch simply removes the print altogether.

commit 69c9189320c46b14e5ae3ad4b3a0d35cc63cba20

    x86 boot: add code to add BIOS provided EFI memory entries to kernel
    
    Add to the kernels boot memory map 'memmap' entries found in
    the EFI memory descriptors passed in from the BIOS.
    
    On EFI systems, up to E820MAX == 128 memory map entries can
    be passed via the legacy E820 interface (limited by the size
    of the 'zeropage').  These entries can be duplicated in the
    EFI descriptors also passed from the BIOS, and possibly more
    entries passed by the EFI interface, which does not have the
    E820MAX limit on number of memory map entries.
    
    This code doesn't worry about the likely duplicate, overlapping
    or (unlikely) conflicting entries between the EFI map and the
    E820 map.  It just dumps all the EFI entries into the memmap[]
    array (which already has the E820 entries) and lets the existing
    routine sanitize_e820_map() sort the mess out.

    it does, what it inputs, and what it returns.  Rearrange the placement of
    this comment to fit kernel conventions, before the routine's code rather

    x86 boot: change sanitize_e820_map parameter from byte to int to allow bigger memory maps
    
    The map size counter passed into, and back out of, sanitize_e820_map(),
    was an eight bit type (char or u8), as derived from its origins in
    legacy BIOS E820 structures.  This patch changes that type to an 'int',
    to allow this sanitize routine to also be used on larger maps (larger
    than the 256 count that fits in a char).  The legacy BIOS E820 interface
    of course does not change; that remains at 8 bits for this count, holding
    up to E820MAX == 128 entries.  But the kernel internals can handle more
    when those additional memory map entries are passed from the BIOS via
    EFI interfaces.

    x86 boot: extend some internal memory map arrays to handle larger EFI input
    
    Extend internal boot time memory tables to allow for up to
    three entries per node, which may be larger than the 128 E820MAX
    entries handled by the legacy BIOS E820 interface.  The EFI
    interface, if present, is capable of passing memory map
    entries for these larger node counts.
    
    This patch requires an earlier patch that rewrote code depending
    on these array sizes from using E820MAX explicitly to size loops,
    to instead using ARRAY_SIZE() of the applicable array.
    
    Another patch following this one will provide the code to pick
    up additional memory entries passed via the EFI interface from
    the BIOS and insert them in the following, now enlarged, arrays.

commit c3965bd15118742d72b4bc1a290d37b3f081eb98
Author: Paul Jackson <pj@sgi.com>

    x86 boot: proper use of ARRAY_SIZE instead of repeated E820MAX constant
    
    This patch is motivated by a subsequent patch which will allow for more
    memory map entries on EFI supported systems than can be passed via the x86
    legacy BIOS E820 interface.  The legacy interface is limited to E820MAX ==
    128 memory entries, and that "E820MAX" manifest constant was used as the
    size for several arrays and loops over those arrays.
    
    The primary change in this patch is to change code loop sizes over those
    arrays from using the constant E820MAX, to using the ARRAY_SIZE() macro
    evaluated for the array being looped.  That way, a subsequent patch can
    change the size of some of these arrays, without breaking this code.
    
    This patch also adds a parameter to the sanitize_e820_map() routine,
    which had an implicit size for the array passed it of E820MAX entries.
    This new parameter explicitly passes the size of said array.  Once again,
    this will allow a subsequent patch to change that array size for some
    calls to sanitize_e820_map() without breaking the code.
    
    As part of enhancing the sanitize_e820_map() interface this way, I further
    combined the unnecessarily distinct x86_32 and x86_64 declarations for
    this routine into a single, commonly used, declaration.
    
    This patch in itself should make no difference to the resulting kernel
    binary.

    x86 boot: simplify pageblock_bits enum declaration
    
    The use of #defines with '##' pre-processor concatenation is a useful
    way to form several symbol names with a common pattern.  But when there
    is just a single name obtained from that #define, it's just obfuscation.
    Better to just write the plain symbol name, as is.
    
    The following patch is a result of my wasting ten minutes looking through
    the kernel to figure out what 'PB_migrate_end' meant, and forgetting what
    I came to do, by the time I figured out that the #define PB_range macro
    defined it.

    when have more than 4g RAM installed, there will be holes below 4g. so need to

    This observation has already been made by Matthew Wilcox in June 2002
    (http://www.cs.helsinki.fi/linux/linux-kernel/2002-25/0687.html)
    
    "I notice that none of the current softirq routines use the data element
    passed to them."
    
    and the situation hasn't changed since them. So it appears we can safely
    remove that extra argument to save 128 (54) bytes of kernel data (text).

    printk: remember the message level for multi-line output
    
    printk(KERN_ALERT "Danger Will Robinson!\nAlien Approaching!\n");
    
    At present this will result in one message at ALERT level and one
    at the current default message loglevel (e.g. WARNING). This is
    non-intuitive.
    
    Modify vprintk() to remember the message loglevel each time it
    is specified and use it for subsequent lines of output which do
    not specify one, within the same call to printk.

    printk: refactor processing of line severity tokens
    
    Restructure the logic of vprintk() so the processing of the leading
    3 characters of each input line is in one place, regardless whether
    printk_time is enabled. This makes the code smaller and easier to
    understand.
    
    size reduction in kernel/printk.o:
    
       text	   data	    bss	    dec	    hex	filename
       6157	    397	1049804	1056358	 101e66	printk.o.before
       6117	    397	1049804	1056318	 101e3e	printk.o.after
    
    and some style uncleanlinesses removed as well as a side-effect:
    
     Before:
        total: 19 errors, 22 warnings, 1340 lines checked

    printk: don't prefer unsuited consoles on registration
    
    console election: If some console happens to be registered first which does
    not provide a tty binding (!console->device), it prevents that more suited
    consoles which are registered later on can enter the candidate pool for
    console_device().  This is observable with KGDB's console which may already
    be registered (and exploited!) during early debugger connections, that is
    before any regular console registration.
    
    This patch fixes the issue by postponing the final, automated
    preferred_console selection until someone with a non-NULL device handler
    comes around.

    ftrace: mmiotrace update, #2
    
    another weekend, another patch. This should apply on top of my previous patch
    from March 23rd.
    
    Summary of changes:
    - Print PCI device list in output header
    - work around recursive probe hits on SMP
    - refactor dis/arm_kmmio_fault_page() and add check for page levels
    - remove un/reference_kmmio(), the die notifier hook is registered
    permanently into the list
    - explicitly check for single stepping in die notifier callback
    
    I have tested this version on my UP Athlon64 desktop with Nouveau, and
    SMP Core 2 Duo laptop with the proprietary nvidia driver. Both systems
    are 64-bit. One previously unknown bug crept into daylight: the ftrace
    framework's output routines print the first entry last after buffer has
    wrapped around.
    
    The most important regressions compared to non-ftrace mmiotrace at this
    time are:
    - failure of trace_pipe file
    - illegal lines in output file
    - unaware of losing data due to buffer full
    
    Personally I'd like to see these three solved before submitting to
    mainline. Other issues may come up once we know when we lose events.

    ftrace: mmiotrace, updates
    
    here is a patch that makes mmiotrace work almost well within the tracing
    framework. The patch applies on top of my previous patch. I have my own
    output formatting in place now.
    
    Summary of changes:
    - fix the NULL dereference that was due to not calling tracing_reset()
    - add print_line() callback into struct tracer
    - implement print_line() for mmiotrace, producing up-to-spec text
    - add my output header, but that is not really called in the right place
    - rewrote the main structs in mmiotrace
    - added two new trace entry types: TRACE_MMIO_RW and TRACE_MMIO_MAP
    - made some functions in trace.c non-static
    - check current==NULL in tracing_generic_entry_update()
    - fix(?) comparison in trace_seq_printf()
    
    Things seem to work fine except a few issues. Markers (text lines injected
    into mmiotrace log) are missing, I did not feel hacking them in before we
    have variable length entries. My output header is printed only for 'trace'
    file, but not 'trace_pipe'. For some reason, despite my quick fix,
    iter->trace is NULL in print_trace_line() when called from 'trace_pipe'
    file, which means I don't get proper output formatting.
    
    I only tried by loading nouveau.ko, which just detects the card, and that
    is traced fine. I didn't try further. Map, two reads and unmap. Works
    perfectly.
    
    I am missing the information about overflows, I'd prefer to have a
    counter for lost events. I didn't try, but I guess currently there is no
    way of knowning when it overflows?
    
    So, not too far from being fully operational, it seems :-)
    And looking at the diffstat, there also is some 700-900 lines of user space
    code that just became obsolete.

    x86: mmiotrace full patch, preview 1
    
    kmmio.c handles the list of mmio probes with callbacks, list of traced
    pages, and attaching into the page fault handler and die notifier. It
    arms, traps and disarms the given pages, this is the core of mmiotrace.
    
    mmio-mod.c is a user interface, hooking into ioremap functions and
    registering the mmio probes. It also decodes the required information
    from trapped mmio accesses via the pre and post callbacks in each probe.
    Currently, hooking into ioremap functions works by redefining the symbols
    of the target (binary) kernel module, so that it calls the traced
    versions of the functions.
    
    The most notable changes done since the last discussion are:
    - kmmio.c is a built-in, not part of the module
    - direct call from fault.c to kmmio.c, removing all dynamic hooks
    - prepare for unregistering probes at any time
    - make kmmio re-initializable and accessible to more than one user
    - rewrite kmmio locking to remove all spinlocks from page fault path
    
    Can I abuse call_rcu() like I do in kmmio.c:unregister_kmmio_probe()
    or is there a better way?
    
    The function called via call_rcu() itself calls call_rcu() again,
    will this work or break? There I need a second grace period for RCU
    after the first grace period for page faults.
    
    Mmiotrace itself (mmio-mod.c) is still a module, I am going to attack
    that next. At some point I will start looking into how to make mmiotrace
    a tracer component of ftrace (thanks for the hint, Ingo). Ftrace should
    make the user space part of mmiotracing as simple as
    'cat /debug/trace/mmio > dump.txt'.

    x86: mmiotrace - trace memory mapped IO
    
    Mmiotrace is a tool for trapping memory mapped IO (MMIO) accesses within
    the kernel. It is used for debugging and especially for reverse
    engineering evil binary drivers.
    
    Mmiotrace works by wrapping the ioremap family of kernel functions and
    marking the returned pages as not present. Access to the IO memory
    triggers a page fault, which will be handled by mmiotrace's custom page
    fault handler. This will single-step the faulted instruction with the
    MMIO page marked as present. Access logs are directed to user space via
    relay and debug_fs.
    
    This page fault approach is necessary, because binary drivers have
    readl/writel etc. calls inlined and therefore extremely difficult to
    trap with with e.g. kprobes.
    
    This patch depends on the custom page fault handlers patch.

    kbuild: create new CFLAGS_REMOVE_(basename).o option
    
    We currently have a way to add special CFLAGS to code, but we do not have a
    way to remove them if needed.
    
    With the case of ftrace, some files should simply not be profiled. Adding
    the -pg flag to these files is simply a waste, and adding "notrace" to each
    and every function is ugly.
    
    Currently we put in "Makefile turd" [1] to stop the compiler from adding -pg
    to certain files. This was clumsy and awkward.
    
    This patch now adds the revese of CFLAGS_(basename).o with
    CFLAGS_REMOVE_(basename).o.  This allows developers to prevent certain
    CFLAGS from being used to compile files. For example, we can now do
    
    CFLAGS_REMOVE_string.o = -pg
    
    to remove the -pg option from the string.o file in the lib directory.
    
    Note: a space delimited list of options may be added to the REMOVE macro.
    
    [1] - what David Miller called the workaronud to remove -pg

    It causes unaligned access traps on platforms like sparc
    (ftrace_page may be marked packed, but once we return
    a dyn_ftrace sub-object from this array to another piece
    of code, the "packed" part of the typing information doesn't
    propagate).
    
    But also, it didn't serve any purpose either.  Even if packed,
    on 64-bit or 32-bit, it didn't give us any more dyn_ftrace
    entries per-page.

    Very good point. I actually thought about dropping it, since it would
    remove an unnecessary argument from the stack. And actually, since I now
    have the marker_probe_cb sitting between the marker site and the
    callbacks, there is no API change required. Thanks :)

    ftrace: limit trace entries
    
    Currently there is no protection from the root user to use up all of
    memory for trace buffers. If the root user allocates too many entries,
    the OOM killer might start kill off all tasks.
    
    This patch adds an algorith to check the following condition:
    
     pages_requested > (freeable_memory + current_trace_buffer_pages) / 4
    
    If the above is met then the allocation fails. The above prevents more
    than 1/4th of freeable memory from being used by trace buffers.
    
    To determine the freeable_memory, I made determine_dirtyable_memory in
    mm/page-writeback.c global.
    
    Special thanks goes to Peter Zijlstra for suggesting the above calculation.

    ftrace: use raw_smp_processor_id for mcount functions
    
    Due to debug hooks in the kernel that can change the way smp_processor_id
    works, use raw_smp_processor_id in mcount called functions (namely
    ftrace_record_ip). Currently we annotate most debug functions from calling
    mcount, but we should not rely on that to prevent kernel lockups.
    
    This patch uses the raw_smp_processor_id to prevent a recusive crash
    that can happen if a debug hook in smp_processor_id calls mcount.

    ftrace: trace_entries to dynamically change trace buffer size
    
    This patch adds /debug/tracing/trace_entries that allows users to
    see as well as modify the number of trace entries the buffers hold.
    
    The number of entries only increments in ENTRIES_PER_PAGE which is
    calculated by the size of an entry with the number of entries that
    can fit in a page. The user does not need to use an exact size, but
    the entries will be rounded to one of the increments.
    
    Trying to set the entries to 0 will return with -EINVAL.
    
    To avoid race conditions, the modification of the buffer size can only
    be done when tracing is completely disabled (current_tracer == none).
    A info message will be printed if a user tries to modify the buffer size
    when not set to none.

    ftrace: fix conversion of task state to char in latency tracer
    
    The conversion of task states to a character in the sched_switch tracer (part
    of latency tracer infrastructure), seems to be incorrect. We currently do it
    by indexing into the state_to_char array using the state value. The state
    values do not map directly into the array index and are thus incorrect. The
    following patch addresses this issue. This is also what is being done even
    in the show_task() routine in kernel/sched.c

    x86: add a list for custom page fault handlers.
    
    Provides kernel modules a way to register custom page fault handlers.
    On every page fault this will call a list of registered functions. The
    functions may handle the fault and force do_page_fault() to return
    immediately.
    
    This functionality is similar to the now removed page fault notifiers.
    Custom page fault handlers are used by debugging and reverse engineering
    tools. Mmiotrace is one such tool and a patch to add it into the tree
    will follow.
    
    The custom page fault handlers are called earlier in do_page_fault()
    than the page fault notifiers were.

    ftrace: do not profile lib/string.o
    
    Most archs define the string and memory compare functions in assembly.
    Some do not. But these functions may be used in some archs at early
    boot up.
    
    Since most archs define this code in assembly and they are not usually
    traced, there's no need to trace them when they are not defined in
    assembly.
    
    This patch removes the -pg from the CFLAGS for lib/string.o.
    This prevents the string functions use in either vdso or early bootup
    from crashing the system.

    ftrace: remove address of function names
    
    PowerPC is very fragile when it comes to use of function names
    and function addresses.  ftrace needs to either use all function
    addresses or function names (i.e. my_func as suppose to &my_func).
    
    This patch chooses to use the names and not the addresses, and
    makes ftrace consistent.

    ftrace: add trace_function api for other tracers to use
    
    A new check was added in the ftrace function that wont trace if the CPU
    trace buffer is disabled.  Unfortunately, other tracers used ftrace() to
    write to the buffer after they disabled it. The new disable check makes
    these calls into a nop.
    
    This patch changes the __ftrace that is called without the check into a
    new api for the other tracers to use, called "trace_function". The other
    tracers use this interface instead when the trace CPU buffer is already
    disabled.

    ftrace - fix dynamic ftrace memory leak
    
    The ftrace dynamic function update allocates a record to store the
    instruction pointers that are being modified. If the modified
    instruction pointer fails to update, then the record is marked as
    failed and nothing more is done.
    
    Worse, if the modification fails, but the record ip function is still
    called, it will allocate a new record and try again. In just a matter
    of time, will this cause a serious memory leak and crash the system.
    
    This patch plugs this memory leak. When a record fails, it is
    included back into the pool of records to be used. Now a record may
    fail over and over again, but the number of allocated records will
    not increase.

    ftrace: user run time file reading
    
    This patch creates a file called trace_pipe in the tracing
    debug directory. This file is a consumer of the trace buffers.
    This means that reads of this file consumes the entries from
    the trace buffers so that they will not be read a second time,
    as contrast to the static buffers latency_trace and trace.
    
    Reading from the trace_pipe will remove the entries from trace
    and latency_trace too.
    
    The advantage that trace_pipe has is that it can record live
    traces. It will block when there is nothing in the buffer,
    and read the entries as they are entered.  An EOF happens when
    tracing is disabled (tracing_enabled = 0).

    ftrace: startup tester on dynamic tracing.
    
    This patch adds a startup self test on dynamic code modification
    and filters. The test filters on a specific function, makes sure that
    no other function is traced, exectutes the function, then makes sure that
    the function is traced.
    
    This patch also fixes a slight bug with the ftrace selftest, where
    tracer_enabled was not being set.

    ftrace: irqs off smp_processor_id() fix
    
    The irqsoff function tracer did a __get_cpu_var to determine
    if it should trace the function or not. The problem is that
    __get_cpu_var can preempt between getting the CPU and reading
    the cpu variable. This means that the cpu variable that is
    being read is not from the cpu being run on.
    
    At worst, this can give a false positive, where we trace the
    function when we should not.  It will never give a false negative
    since we only want to trace when interrupts are disabled
    and we never preempt when they are.
    
    This fix adds a check after reading the irq flags to only
    trace if the interrupts are actually disabled. It also changes
    the reading of the cpu variable to use a raw_smp_processor_id
    since we now don't care if we preempt. We still catch that fact.

    ftrace: debug smp_processor_id, use notrace preempt disable
    
    The debug smp_processor_id caused a recursive fault in debugging
    the irqsoff tracer. The tracer used a smp_processor_id in the
    ftrace callback, and this function called preempt_disable which
    also is traced. This caused a recursive fault (stack overload).
    
    Since using smp_processor_id without debugging on does not cause
    faults with the tracer (even when the tracer is wrong), the
    debug version should not cause a system reboot.
    
    This changes the debug_smp_processor_id to use the notrace versions
    of preempt_disable and enable.

    ftrace: add filter select functions to trace
    
    This patch adds two files to the debugfs system:
    
     /debugfs/tracing/available_filter_functions
    
    and
    
     /debugfs/tracing/set_ftrace_filter
    
    The available_filter_functions lists all functions that has been
    recorded by the ftraced that has called the ftrace_record_ip function.
    This is to allow users to see what functions have been converted
    to nops and can be enabled for tracing.
    
    To enable functions, simply echo the names (whitespace delimited)
    into set_ftrace_filter. Simple wildcards are also allowed.
    
    echo 'scheduler' > /debugfs/tracing/set_ftrace_filter
    
    Will have only the scheduler be activated when tracing is enabled.
    
    echo 'sched_*' > /debugfs/tracing/set_ftrace_filter
    
    Will have only the functions starting with 'sched_' be activated.
    
    echo '*lock' > /debugfs/tracing/set_ftrace_filter
    
    Will have only functions ending with 'lock' be activated.
    
    echo '*lock*' > /debugfs/tracing/set_ftrace_filter
    
    Will have only functions with 'lock' in its name be activated.
    
    Note: 'sched*lock' will not work. The only wildcards that are
    allowed is an asterisk and the beginning and or end of the string
    passed in.
    
    Multiple names can be passed in with whitespace delimited:
    
    echo 'scheduler *lock *acpi*' > /debugfs/tracing/set_ftrace_filter
    
    is also the same as:
    
    echo 'scheduler' > /debugfs/tracing/set_ftrace_filter
    echo '*lock' >> /debugfs/tracing/set_ftrace_filter
    echo '*acpi*' >> /debugfs/tracing/set_ftrace_filter
    
    Appending does just that. It appends to the list.
    
    To disable all filters simply echo an empty line in:
    
    echo > /debugfs/tracing/set_ftrace_filter

    ftrace: use dynamic patching for updating mcount calls
    
    This patch replaces the indirect call to the mcount function
    pointer with a direct call that will be patched by the
    dynamic ftrace routines.
    
    On boot up, the mcount function calls the ftace_stub function.
    When the dynamic ftrace code is initialized, the ftrace_stub
    is replaced with a call to the ftrace_record_ip, which records
    the instruction pointers of the locations that call it.
    
    Later, the ftraced daemon will call kstop_machine and patch all
    the locations to nops.
    
    When a ftrace is enabled, the original calls to mcount will now
    be set top call ftrace_caller, which will do a direct call
    to the registered ftrace function. This direct call is also patched
    when the function that should be called is updated.
    
    All patching is performed by a kstop_machine routine to prevent any
    type of race conditions that is associated with modifying code
    on the fly.

    ftrace: dynamic enabling/disabling of function calls
    
    This patch adds a feature to dynamically replace the ftrace code
    with the jmps to allow a kernel with ftrace configured to run
    as fast as it can without it configured.
    
    The way this works, is on bootup (if ftrace is enabled), a ftrace
    function is registered to record the instruction pointer of all
    places that call the function.
    
    Later, if there's still any code to patch, a kthread is awoken
    (rate limited to at most once a second) that performs a stop_machine,
    and replaces all the code that was called with a jmp over the call
    to ftrace. It only replaces what was found the previous time. Typically
    the system reaches equilibrium quickly after bootup and there's no code
    patching needed at all.
    
    e.g.
    
      call ftrace  /* 5 bytes */
    
    is replaced with
    
      jmp 3f  /* jmp is 2 bytes and we jump 3 forward */
    3:
    
    When we want to enable ftrace for function tracing, the IP recording
    is removed, and stop_machine is called again to replace all the locations
    of that were recorded back to the call of ftrace.  When it is disabled,
    we replace the code back to the jmp.
    
    Allocation is done by the kthread. If the ftrace recording function is
    called, and we don't have any record slots available, then we simply
    skip that call. Once a second a new page (if needed) is allocated for
    recording new ftrace function calls.  A large batch is allocated at
    boot up to get most of the calls there.
    
    Because we do this via stop_machine, we don't have to worry about another
    CPU executing a ftrace call as we modify it. But we do need to worry
    about NMI's so all functions that might be called via nmi must be
    annotated with notrace_nmi. When this code is configured in, the NMI code
    will not call notrace.

    ftrace: trace preempt off critical timings
    
    Add preempt off timings. A lot of kernel core code is taken from the RT patch
    latency trace that was written by Ingo Molnar.
    
    This adds "preemptoff" and "preemptirqsoff" to /debugfs/tracing/available_tracers
    
    Now instead of just tracing irqs off, preemption off can be selected
    to be recorded.
    
    When this is selected, it shares the same files as irqs off timings.
    One can either trace preemption off, irqs off, or one or the other off.
    
    By echoing "preemptoff" into /debugfs/tracing/current_tracer, recording
    of preempt off only is performed. "irqsoff" will only record the time
    irqs are disabled, but "preemptirqsoff" will take the total time irqs
    or preemption are disabled. Runtime switching of these options is now
    supported by simpling echoing in the appropriate trace name into
    /debugfs/tracing/current_tracer.

    ftrace: trace irq disabled critical timings
    
    This patch adds latency tracing for critical timings
    (how long interrupts are disabled for).
    
     "irqsoff" is added to /debugfs/tracing/available_tracers
    
    Note:
      tracing_max_latency
        also holds the max latency for irqsoff (in usecs).
       (default to large number so one must start latency tracing)
    
      tracing_thresh
        threshold (in usecs) to always print out if irqs off
        is detected to be longer than stated here.
        If irq_thresh is non-zero, then max_irq_latency
        is ignored.
    
    Here's an example of a trace with ftrace_enabled = 0

    ftrace: tracer for scheduler wakeup latency
    
    This patch adds the tracer that tracks the wakeup latency of the
    highest priority waking task.
    
      "wakeup" is added to /debugfs/tracing/available_tracers
    
    Also added to /debugfs/tracing
    
      tracing_max_latency
         holds the current max latency for the wakeup
    
      wakeup_thresh
         if set to other than zero, a log will be recorded
         for every wakeup that takes longer than the number
         entered in here (usecs for all counters)
         (deletes previous trace)
    
    Examples:
    
      (with ftrace_enabled = 0)

    ftrace: function tracer
    
    This is a simple trace that uses the ftrace infrastructure. It is
    designed to be fast and small, and easy to use. It is useful to
    record things that happen over a very short period of time, and
    not to analyze the system in general.
    
     Updates:
    
      available_tracers
         "function" is added to this file.
    
      current_tracer
        To enable the function tracer:
    
          echo function > /debugfs/tracing/current_tracer
    
         To disable the tracer:
    
           echo disable > /debugfs/tracing/current_tracer
    
    The output of the function_trace file is as follows
    
      "echo noverbose > /debugfs/tracing/iter_ctrl"

    ftrace: latency tracer infrastructure
    
    This patch adds the latency tracer infrastructure. This patch
    does not add anything that will select and turn it on, but will
    be used by later patches.
    
    If it were to be compiled, it would add the following files
    to the debugfs:
    
     The root tracing directory:
    
      /debugfs/tracing/
    
    This patch also adds the following files:
    
      available_tracers
         list of available tracers. Currently no tracers are
         available. Looking into this file only shows
         "none" which is used to unregister all tracers.
    
      current_tracer
         The trace that is currently active. Empty on start up.
         To switch to a tracer simply echo one of the tracers that
         are listed in available_tracers:
    
       example: (used with later patches)
    
          echo function > /debugfs/tracing/current_tracer
    
         To disable the tracer:
    
           echo disable > /debugfs/tracing/current_tracer
    
      tracing_enabled
         echoing "1" into this file starts the ftrace function tracing
          (if sysctl kernel.ftrace_enabled=1)
         echoing "0" turns it off.
    
      latency_trace
          This file is readonly and holds the result of the trace.
    
      trace
          This file outputs a easier to read version of the trace.
    
      iter_ctrl
          Controls the way the output of traces look.
          So far there's two controls:
            echoing in "symonly" will only show the kallsyms variables
                without the addresses (if kallsyms was configured)
            echoing in "verbose" will change the output to show
                a lot more data, but not very easy to understand by
                humans.
            echoing in "nosymonly" turns off symonly.
            echoing in "noverbose" turns off verbose.

    ftrace: add basic support for gcc profiler instrumentation
    
    If CONFIG_FTRACE is selected and /proc/sys/kernel/ftrace_enabled is
    set to a non-zero value the ftrace routine will be called everytime
    we enter a kernel function that is not marked with the "notrace"
    attribute.
    
    The ftrace routine will then call a registered function if a function
    happens to be registered.
    
    [ This code has been highly hacked by Steven Rostedt and Ingo Molnar,
      so don't blame Arnaldo for all of this ;-) ]
    
    Update:
      It is now possible to register more than one ftrace function.
      If only one ftrace function is registered, that will be the
      function that ftrace calls directly. If more than one function
      is registered, then ftrace will call a function that will loop
      through the functions to call.

    tracing: add notrace to linkage.h
    
    notrace signals that a function should not be traced. Most of the
    time this is used by tracers to annotate code that cannot be
    traced - it's in a volatile state (such as in user vdso context
    or NMI context) or it's in the tracer internals.

    [POWERPC] Add debugging trigger to Axon MSI code
    
    This adds some debugging code to the Axon MSI driver.  It creates a
    file per MSIC in /sys/kernel/debug/powerpc, which allows the user to
    trigger a fake MSI interrupt by writing to the file.
    
    This can be used to test some of the MSI generation path.  In
    particular, that the MSIC recognises a write to the MSI address,
    generates an interrupt and writes the MSI packet into the ring buffer.
    
    All the code is inside #ifdef DEBUG so it causes no harm unless it's
    enabled.

    Debugging this showed that the NODE_DATA() for nodes other than node 0
    were all NULL.  Tracing this back showed that the NODE_DATA() pointers
    were being initialised to each nodes remap space.  However under
    SPARSEMEM remap is disabled which leads to the pgdat's being placed
    incorrectly at kernel virtual address 0.  Leading to the panic when
    attempting to allocate memory from these nodes.
    
    Numa remap was disabled in the commit below.  This occured while fixing
    problems triggered when attempting to boot x86_32 NUMA SPARSEMEM kernels
    on non-numa hardware.
    
    	x86: make NUMA work on 32-bit
    	commit 1b000a5dbeb2f34bc03d45ebdf3f6d24a60c3aed
    
    The real problem is believed to be related to other alignment issues in
    the regions blocked out from the bootmem allocator for small memory
    systems, and has been fixed separately.  Therefore re-enable remap for
    SPARSMEM, which fixes pgdat allocation issues.  Testing confirms that
    SPARSMEM NUMA kernels will boot correctly with this part of the change
    reverted.

    [ALSA] soc - Fix s3c24xx-i2s LR sync while timer ticks are disabled
    
    When timer ticks are disabled when calling
    sound/soc/s3c24xx/s3c24xx-i2s.c:s3c24xx_snd_lrsync
    and the LR signal never happens, we loop forever.
    This has been observed in the following call chain:
    snd_pcm_common_ioctl1 -> snd_pcm_action_lock_irq ->
    snd_pcm_action_single
     -> snd_pcm_do_resume -> soc_pcm_trigger -> s3c24xx_i2s_trigger
    
    The patch below changes the timeout mechanism to use udelay, which
    doesn't need timer ticks.

    [ALSA] ASoC: Clarify API for bias configuration
    
    Currently the ASoC core configures the bias levels in the system using
    a callback on codecs and machines called 'dapm_event', passing it PCI
    style power levels as SNDRV_CTL_POWER_ constants. This is more obscure
    than it needs to be and has caused confusion to driver authors,
    especially given that DAPM is also performing power management.
    
    Address this by renaming the callback function to 'set_bias_level' and
    using constants explicitly representing the off, standby, pre-on and on
    states which DAPM transitions through.
    
    Also unexport the API for setting bias level: there are currently no
    in-tree users of this API other than the core itself and it is likely
    that the core would need to be extended to cater for any users.

    [ARM] pxa: separate PXA25x and PXA27x UDC register definitions
    
    The PXA25x and PXA27x USB device controller register definitions are
    different.  Currently, they live side by side in pxa-regs.h, but only
    one set is available depending on the setting of PXA25x or PXA27x.
    
    This means that if we build to support both PXA25x and PXA27x, the
    PXA27x definitions are unavailable, even to PXA27x specific code.
    
    Remove these definitions from pxa-regs.h, and place them in separate
    files.  Include these files where appropriate.
    
    Note: according to the dependencies in drivers/usb/gadget/Kconfig,
    we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the
    platform devices from pxa27x.c and pxa3xx.c.

    Note: PWM0 and PWM2 share the same register I/O space and clock gating
    on pxa{27x, 3xx}, thus PWM2 is treated in the driver as a child PWM of
    PWM0. And this is also true for PWM1/3.

    JACK doesn't work with two periods.
    
    This patch fixes the problem by checking the current DMA position
    at IRQ handler and delays the period-update via a workq if it's

    [ALSA] PCI168 snd-azt3328 Linux driver: another huge update
    
    - figured out 'Digital(ly) Enhanced Game Port' functionality,
      implemented support for it (eliminating gameport polling overhead)
    - removed optional joystick activation, gameport now enabled unconditionally,
      since we now support it via the PCI I/O space, not via conflict-prone
      legacy I/O (which I was thus able to DISABLE now)!
    - fix playback bug (a muted wave output would get unmuted upon start of
      playback, of course this is not what we want, thus remember mute state)
    - implement partial power management: when idle, lower clock rate and disable
      codec (reduced noise!), and disable gameport circuit when unused
    - instantiate OPL3 timer, too
    - much better implementation of snd_azf3328_mixer_write_volume_gradually()
    - slightly optimized interrupt handling
    - lots of cleanup
    
    This time, I also found a way to verify proper OPL3 operation
    via MIDI file playback (emulation via synth hardware).

    rcu: fix rcu_try_flip_waitack_needed() to prevent grace-period stall
    
    The comment was correct -- need to make the code match the comment.
    Without this patch, if a CPU goes dynticks idle (and stays there forever)
    in just the right phase of preemptible-RCU grace-period processing,
    grace periods stall.  The offending sequence of events (courtesy
    of Promela/spin, at least after I got the liveness criterion coded
    correctly...) is as follows:
    
    o	CPU 0 is in dynticks-idle mode.  Its dynticks_progress_counter
    	is (say) 10.
    
    o	CPU 0 takes an interrupt, so rcu_irq_enter() increments CPU 0's
    	dynticks_progress_counter to 11.
    
    o	CPU 1 is doing RCU grace-period processing in rcu_try_flip_idle(),
    	sees rcu_pending(), so invokes dyntick_save_progress_counter(),
    	which in turn takes a snapshot of CPU 0's dynticks_progress_counter
    	into CPU 0's rcu_dyntick_snapshot -- now set to 11.  CPU 1 then
    	updates the RCU grace-period state to rcu_try_flip_waitack().
    
    o	CPU 0 returns from its interrupt, so rcu_irq_exit() increments
    	CPU 0's dynticks_progress_counter to 12.
    
    o	CPU 1 later invokes rcu_try_flip_waitack(), which notices that
    	CPU 0 has not yet responded, and hence in turn invokes
    	rcu_try_flip_waitack_needed().  This function examines the
    	state of CPU 0's dynticks_progress_counter and rcu_dyntick_snapshot
    	variables, which it copies to curr (== 12) and snap (== 11),
    	respectively.
    
    	Because curr!=snap, the first condition fails.
    
    	Because curr-snap is only 1 and snap is odd, the second
    	condition fails.
    
    	rcu_try_flip_waitack_needed() therefore incorrectly concludes
    	that it must wait for CPU 0 to explicitly acknowledge the
    	counter flip.
    
    o	CPU 0 remains forever in dynticks-idle mode, never taking
    	any more hardware interrupts or any NMIs, and never running
    	any more tasks.  (Of course, -something- will usually eventually
    	happen, which might be why we haven't seen this one in the
    	wild.  Still should be fixed!)
    
    Therefore the grace period never ends.  Fix is to make the code match
    the comment, as shown below.  With this fix, the above scenario
    would be satisfied with curr being even, and allow the grace period
    to proceed.

    rcu: split list.h and move rcu-protected lists into rculist.h
    
    Move rcu-protected lists from list.h into a new header file rculist.h.
    
    This is done because list are a very used primitive structure all over the
    kernel and it's currently impossible to include other header files in this
    list.h without creating some circular dependencies.
    
    For example, list.h implements rcu-protected list and uses rcu_dereference()
    without including rcupdate.h.  It actually compiles because users of
    rcu_dereference() are macros.  Others RCU functions could be used too but
    aren't probably because of this.
    
    Therefore this patch creates rculist.h which includes rcupdates without to
    many changes/troubles.

    rcu: add call_rcu_sched()
    
    Fourth cut of patch to provide the call_rcu_sched().  This is again to
    synchronize_sched() as call_rcu() is to synchronize_rcu().
    
    Should be fine for experimental and -rt use, but not ready for inclusion.
    With some luck, I will be able to tell Andrew to come out of hiding on
    the next round.
    
    Passes multi-day rcutorture sessions with concurrent CPU hotplugging.
    
    Fixes since the first version include a bug that could result in
    indefinite blocking (spotted by Gautham Shenoy), better resiliency
    against CPU-hotplug operations, and other minor fixes.
    
    Fixes since the second version include reworking grace-period detection
    to avoid deadlocks that could happen when running concurrently with
    CPU hotplug, adding Mathieu's fix to avoid the softlockup messages,
    as well as Mathieu's fix to allow use earlier in boot.
    
    Fixes since the third version include a wrong-CPU bug spotted by
    Andrew, getting rid of the obsolete synchronize_kernel API that somehow
    snuck back in, merging spin_unlock() and local_irq_restore() in a
    few places, commenting the code that checks for quiescent states based
    on interrupting from user-mode execution or the idle loop, removing
    some inline attributes, and some code-style changes.
    
    Known/suspected shortcomings:
    
    o	I still do not entirely trust the sleep/wakeup logic.  Next step
    	will be to use a private snapshot of the CPU online mask in
    	rcu_sched_grace_period() -- if the CPU wasn't there at the start
    	of the grace period, we don't need to hear from it.  And the
    	bit about accounting for changes in online CPUs inside of
    	rcu_sched_grace_period() is ugly anyway.
    
    o	It might be good for rcu_sched_grace_period() to invoke
    	resched_cpu() when a given CPU wasn't responding quickly,
    	but resched_cpu() is declared static...
    
    This patch also fixes a long-standing bug in the earlier preemptable-RCU
    implementation of synchronize_rcu() that could result in loss of
    concurrent external changes to a task's CPU affinity mask.  I still cannot
    remember who reported this...

    rcupreempt: remove duplicate prototypes
    
    rcu_batches_completed and rcu_patches_completed_bh are both declared
    in rcuclassic.h and rcupreempt.h. This patch removes the extra
    prototypes for them from rcupdate.h.
    
    rcu_batches_completed_bh is defined as a static inline in the rcupreempt.h
    header file. Trying to export this as EXPORT_SYMBOL_GPL causes linking problems
    with the powerpc linker. There's no need to export a static inlined function.
    
    Modules must be compiled with the same type of RCU implementation as the
    kernel they are for.

    mutex-debug: check mutex magic before owner
    
    Currently, the mutex debug code checks the lock->owner before lock->magic, so
    a corrupt mutex will most likely result in failing the owner check, rather
    than the magic check.
    
    This change to debug_mutex_unlock does the magic check first, so
    we have a better idea of what breaks.

    [POWERPC] Add 6xx-style HID0_SLEEP support.
    
    This adds a function to put a 6xx/7xx/7xxx/83xx family CPU into sleep
    mode, and return after an interrupt has occurred.  It expects to be
    called with interrupts disabled, and returns with interrupts disabled.
    Interrupts are enabled while the processor is asleep, but the interrupt
    that wakes the processor is not handled; it is still pending when this
    function returns.

Date:   Wed May 14 14:30:48 2008 +1000

    [POWERPC] Defer processing of interrupts when the CPU wakes from sleep mode
    
    This provides a way to defer processing of an interrupt that wakes the
    processor out of sleep mode.  On 32-bit platforms that use an
    interrupt to wake the processor, we have to have interrupts enabled in
    hardware at the point where we go to sleep, otherwise the processor
    will never wake up.  However, because interrupts are logically
    disabled at this point, we don't want to process the interrupt
    straight away.
    
    This is handled by setting the _TLF_SLEEPING flag.  When we get an
    interrupt and _TLF_SLEEPING is set, we firstly clear the MSR_EE
    (external interrupt enable) bit in the saved MSR value, and secondly
    we then return to the address in the link register, like we do for
    _TLF_NAPPING, but without actually handling the interrupt.
    
    Note that this is handled somewhat differently on powerbooks, so this
    new code will only be used on non-Apple machines.

    x86_64: allocate gart aperture from 512M
    
    because we try to reserve dma32 early, so we have chance to get aperture
    from 64M.
    
    with some sequence aperture allocated from RAM, could become E820_RESERVED.
    
    and then if doing a kexec with a big kernel that uncompressed size is above
    64M we could have a range conflict with still using gart.
    
    So allocate gart aperture from 512M instead.
    
    Also change the fallback_aper_order to 5, because we don't have chance to get
    2G or 4G aperture.

    x86: checking aperture size order
    
    some systems are using 32M for gart and agp when memory is less than 4G.
    Kernel will reject and try to allcate another 64M that is not needed,
    and we will waste 64M of perfectly good RAM.
    
    this patch adds a workaround by checking aper_base/order between NB and
    agp bridge. If they are the same, and memory size is less than 4G, it
    will allow it.

    x86: agp_gart size checking for buggy device
    
    while looking at Rafael J. Wysocki's system boot log,
    
    I found a funny printout:
    
    	Node 0: aperture @ de000000 size 32 MB
    	Aperture too small (32 MB)
    	AGP bridge at 00:04:00
    	Aperture from AGP @ de000000 size 4096 MB (APSIZE 0)
    	Aperture too small (0 MB)
    	Your BIOS doesn't leave a aperture memory hole
    	Please enable the IOMMU option in the BIOS setup
    	This costs you 64 MB of RAM
    	Mapping aperture over 65536 KB of RAM @ 4000000
    
    	...
    
    	agpgart: Detected AGP bridge 20
    	agpgart: Aperture pointing to RAM
    	agpgart: Aperture from AGP @ de000000 size 4096 MB
    	agpgart: Aperture too small (0 MB)
    	agpgart: No usable aperture found.
    	agpgart: Consider rebooting with iommu=memaper=2 to get a good aperture.
    
    it means BIOS allocated the correct gart on the NB and AGP bridge, but
    because a bug in the silicon (the agp bridge reports the wrong order,
    it wants 4G instead) the kernel will reject that allocation.
    
    Also, because the size is only 32MB, and we try to get another 64M for gart,
    late fix_northbridge can not revert that change because it still reads
    the wrong size from agp bridge.
    
    So try to double check the order value from the agp bridge, before calling
    aperture_valid().

    i386: Execute stack overflow warning on interrupt stack v2
    
    Previously the reporting printk would run on the process stack, which risks
    overflow an already low stack. Instead execute it on the interrupt stack.
    This makes it more likely for the printk to make it actually out.
    
    It adds one not taken test/branch more to the interrupt path when
    stack overflow checking is enabled. We could avoid that by duplicating
    more code, but that seemed not worth it.
    
    Based on an observation by Eric Sandeen.

    x86: common thread_info definitions
    
    Merge the thread_info definition into one structure definition for both arches.
    
    The __u32 is equal to unsigned long for 32 bit.
    
    sysenter_return is used both for the IA32 emulation for 64 and x86_32.
    Avoid complicated #ifdef by simply always including it.

    x86: remove 6 bank limitation in 64 bit MCE reporting code
    
    Eliminate the 6 bank restriction in 64 bit mce reporting code. This
    restriction is artificial (due to static creation of sysfs files) and 32
    bit code does not have any such restriction.
    
    This change helps in reporting the details of machine checks on a
    machine check exception with errors in bank 6 and above on CPUs that
    support those banks. Without the patch, machine check errors in those
    banks are not reported.
    
    We still have 128 (MCE_EXTENDED_BANK) bank restriction instead of max
    256 supported in hardware. That is not changed in the patch below as it
    will have some user level mcelog utility dependency, with bank 128 being
    used for thermal reporting currently.
    
    The patch below does not create sysfs control (bankNctl) for banks
    higher than 6 as well. That needs some pre-cleanup in /sysfs mce layout,
    removal of per cpu /sysfs entries for bankctl as they are really global
    system level control today. That change will follow. This basic change
    is critical to report the detailed errors on banks higher than 6.

    x86: print info about available HPET quirk
    
    We have a lot of HPET quirks available which might force enable HPET
    even when the BIOS does not enable it. Some of those quirks depend on
    the command line option "hpet=force".
    
    Andrew pointed out that hoping that the user will find out about this
    boot option is not really helpful.
    
    Emit a kernel info which informs the user about the "hpet=force" boot
    option when we enter a quirk which depends on this option and the user
    did not provide it.

    x86: clean up computation of HPET .mult variables
    
    While reading through the HPET code I realized that the
    computation of .mult variables could be done with less
    lines of code, resulting in a 1.6% text size saving
    for hpet.o
    
    So I propose the following patch, which applies against
    today's Linus -git tree.
    
    >From 0c6507e400e9ca5f7f14331e18f8c12baf75a9d3 Mon Sep 17 00:00:00 2001
    From: Carlos R. Mafra <crmafra@ift.unesp.br>
    Date: Mon, 5 May 2008 19:38:53 -0300
    
    The computation of clocksource_hpet.mult
    
           tmp = (u64)hpet_period << HPET_SHIFT;
           do_div(tmp, FSEC_PER_NSEC);
           clocksource_hpet.mult = (u32)tmp;
    
    can be streamlined if we note that it is equal to
    
           clocksource_hpet.mult = div_sc(hpet_period, FSEC_PER_NSEC, HPET_SHIFT);
    
    Furthermore, the computation of hpet_clockevent.mult
    
           uint64_t hpet_freq;
    
           hpet_freq = 1000000000000000ULL;
           do_div(hpet_freq, hpet_period);
           hpet_clockevent.mult = div_sc((unsigned long) hpet_freq,
                                         NSEC_PER_SEC, hpet_clockevent.shift);
    
    can also be streamlined with the observation that hpet_period and hpet_freq are
    inverse to each other (in proper units).
    
    So instead of computing hpet_freq and using (schematically)
    div_sc(hpet_freq, 10^9, shift) we use the trick of calling with the
    arguments in reverse order, div_sc(10^6, hpet_period, shift).
    
    The different power of ten is due to frequency being in Hertz (1/sec)
    and the period being in units of femtosecond. Explicitly,
    
    mult = (hpet_freq * 2^shift)/10^9    (before)
    mult = (10^6 * 2^shift)/hpet_period  (after)
    
    because hpet_freq = 10^15/hpet_period.
    
    The comments in the code are also updated to reflect the changes.
    
    As a result,
    
       text    data     bss     dec     hex filename
       2957     425      92    3474     d92 arch/x86/kernel/hpet.o
       3006     425      92    3523     dc3 arch/x86/kernel/hpet.o.old
    
    a 1.6% reduction in text size.

    This does not seem to be a recent breakage.
    
    The ARCH_CO285 support is old - kernel 2.2.0 contains first traces of
    it, an it seems to have been pretty complete in later 2.2 kernels.
    
    Since it seems to be completely dead code now this patch therefore
    removes it.

    The Freecom-FSG3 is a small network-attached-storage device with the
    following feature set:
    
    * Intel IXP422
    * 4MB Flash (ixp4xx flash driver)
    * 64MB RAM
    * 4 USB 2.0 host ports (ehci and ohci drivers)
    * 1 WAN (eth1) and 3 LAN (eth0) ethernet ports
      * Supported by the open source ixp4xx ethernet driver
    * Via VT6421 disk controller (libata and sata-via drivers)
      * Internal hard disk (PATA supported, SATA not yet supported)
      * External SATA port (not yet supported)
    * ISL1208 RTC chip
    * Winbond 83782 temp sensor and fan controller
    * MiniPCI slot
    
    The ixp4xx_defconfig is also updated to support this device (the
    leds-fsg driver is to be submitted separately via the leds tree after
    this initial support is merged, as it depends on header gpio defines).
