    pch_uart: fix a deadlock when pch_uart as console

    commit 384e301e3519599b000c1a2ecd938b533fc15d85 upstream.

    When we use pch_uart as system console like 'console=ttyPCH0,115200',
    then 'send break' to it. We'll encounter the deadlock on a cpu/core,
    with interrupts disabled on the core. When we happen to have all irqs
    affinity to cpu0 then the deadlock on cpu0 actually deadlock whole
    system.

    In pch_uart_interrupt, we have spin_lock_irqsave(&priv->lock, flags)
    then call pch_uart_err_ir when break is received. Then the call to
    dev_err would actually call to pch_console_write then we'll run into
    another spin_lock(&priv->lock), with interrupts disabled.

    So in the call sequence lead by pch_uart_interrupt, we should be
    carefully to call functions that will 'print message to console' only
    in case the uart port is not being used as serial console.

    UBIFS: fix a horrid bug

    commit 605c912bb843c024b1ed173dc427cd5c08e5d54d upstream.

    Al Viro pointed me to the fact that '->readdir()' and '->llseek()' have no
    mutual exclusion, which means the 'ubifs_dir_llseek()' can be run while we are
    in the middle of 'ubifs_readdir()'.

    This means that 'file->private_data' can be freed while 'ubifs_readdir()' uses
    it, and this is a very bad bug: not only 'ubifs_readdir()' can return garbage,
    but this may corrupt memory and lead to all kinds of problems like crashes an
    security holes.

    This patch fixes the problem by using the 'file->f_version' field, which
    '->llseek()' always unconditionally sets to zero. We set it to 1 in
    'ubifs_readdir()' and whenever we detect that it became 0, we know there was a
    seek and it is time to clear the state saved in 'file->private_data'.

    I tested this patch by writing a user-space program which runds readdir and
    seek in parallell. I could easily crash the kernel without these patches, but
    could not crash it with these patches.

    UBIFS: prepare to fix a horrid bug

    commit 33f1a63ae84dfd9ad298cf275b8f1887043ced36 upstream.

    Al Viro pointed me to the fact that '->readdir()' and '->llseek()' have no
    mutual exclusion, which means the 'ubifs_dir_llseek()' can be run while we are
    in the middle of 'ubifs_readdir()'.

    First of all, this means that 'file->private_data' can be freed while
    'ubifs_readdir()' uses it.  But this particular patch does not fix the problem.
    This patch is only a preparation, and the fix will follow next.

    In this patch we make 'ubifs_readdir()' stop using 'file->f_pos' directly,
    because 'file->f_pos' can be changed by '->llseek()' at any point. This may
    lead 'ubifs_readdir()' to returning inconsistent data: directory entry names
    may correspond to incorrect file positions.

    So here we introduce a local variable 'pos', read 'file->f_pose' once at very
    the beginning, and then stick to 'pos'. The result of this is that when
    'ubifs_dir_llseek()' changes 'file->f_pos' while we are in the middle of
    'ubifs_readdir()', the latter "wins".

    perf: Disable monitoring on setuid processes for regular users

    commit 2976b10f05bd7f6dab9f9e7524451ddfed656a89 upstream.

    There was a a bug in setup_new_exec(), whereby
    the test to disabled perf monitoring was not
    correct because the new credentials for the
    process were not yet committed and therefore
    the get_dumpable() test was never firing.

    The patch fixes the problem by moving the
    perf_event test until after the credentials
    are committed.

    hw_breakpoint: Use cpu_possible_mask in {reserve,release}_bp_slot()

    commit c790b0ad23f427c7522ffed264706238c57c007e upstream.

    fetch_bp_busy_slots() and toggle_bp_slot() use
    for_each_online_cpu(), this is obviously wrong wrt cpu_up() or
    cpu_down(), we can over/under account the per-cpu numbers.

    For example:

        # echo 0 >> /sys/devices/system/cpu/cpu1/online
        # perf record -e mem:0x10 -p 1 &
        # echo 1 >> /sys/devices/system/cpu/cpu1/online

    If a too small MTU value is set with ioctl(HCISETACLMTU) or by a bogus
    controller, memory corruption happens due to a memcpy() call with
    negative length.

    Fix this crash on either incoming or outgoing connections with a MTU

fuse: fix nlink after unlink

Anand Avati reports that the following sequence of system calls fail on a fuse
filesystem:

 	create("filename") => 0
 	link("filename", "linkname") => 0
 	unlink("filename") => 0
 	link("linkname", "filename") => -ENOENT ### BUG ###

vfs_link() fails with ENOENT if i_nlink is zero, this is done to prevent
resurrecting already deleted files.

Fuse clears i_nlink on unlink even if there are other links pointing to the
file.

fuse: O_DIRECT support for files

Implement ->direct_IO() method in aops. The ->direct_IO() method combines
the existing fuse_direct_read/fuse_direct_write methods to implement
O_DIRECT functionality.

Reaching ->direct_IO() in the read path via generic_file_aio_read ensures
proper synchronization with page cache with its existing framework.

Reaching ->direct_IO() in the write path via fuse_file_aio_write is made
to come via generic_file_direct_write() which makes it play nice with
the page cache w.r.t other mmap pages etc.

On files marked 'direct_io' by the filesystem server, IO always follows
the fuse_direct_read/write path. There is no effect of fcntl(O_DIRECT)
and it always succeeds.

On files not marked with 'direct_io' by the filesystem server, the IO
path depends on O_DIRECT flag by the application. This can be passed
at the time of open() as well as via fcntl().

Note that asynchronous O_DIRECT iocb jobs are completed synchronously
always (this has been the case with FUSE even before this patch)

fuse: fix stat call on 32 bit platforms

commit 45c72cd73c788dd18c8113d4a404d6b4a01decf1 upstream.

Now we store attr->ino at inode->i_ino, return attr->ino at the
first time and then return inode->i_ino if the attribute timeout
isn't expired. That's wrong on 32 bit platforms because attr->ino
is 64 bit and inode->i_ino is 32 bit in this case.

Fix this by saving 64 bit ino in fuse_inode structure and returning
it every time we call getattr. Also squash attr->ino into inode->i_ino
explicitly.

mm: pass readahead info down to the i/o scheduler

Some i/o schedulers (i.e. row-iosched, cfq-iosched) deploy an idling
algorithm in order to be better synced with the readahead algorithm.
Idling is a prediction algorithm for incoming read requests.

In this patch we mark pages which are part of a readahead window, by
setting a newly introduced flag. With this flag, the i/o scheduler can
identify a request which is associated with a readahead page. This
enables the i/o scheduler's idling mechanism to be en-sync with the
readahead mechanism and, in turn, can increase read throughput.

block: row-iosched idling triggered by readahead pages

In the current implementation idling is triggered only by request
insertion frequency. This heuristic is not very accurate and may hit
random requests that shouldn't trigger idling. This patch uses the
PG_readahead flag in struct page's flags, which indicates that the page
is part of a readahead window, to start idling upon dispatch of a request
associated with a readahead page.

The above readehead flag is used together with the existing
insertion-frequency trigger. The frequency timer will catch read requests
which are not part of a readahead window, but are still part of a
sequential stream (and therefore dispatched in small time intervals).

staging: zsmalloc: zsmalloc memory allocation library

This patch creates a new memory allocation library named
zsmalloc.

NOTE: zsmalloc currently depends on SPARSEMEM for the MAX_PHYSMEM_BITS
value needed to determine the format of the object handle. There may
be a better way to do this.  Feedback is welcome.

staging: fix powerpc linux-next break on zsmalloc

linux/vmalloc.h added to zsmalloc-main.c to resolve implicit
declaration errors.

X86 dependency added to zsmalloc and dependent drivers zcache and zram.

This X86 only requirement is not ideal.  Working to find portable
functions for __flush_tlb_one and set_pte.

staging: zsmalloc: move object/handle masking defines

This patch moves the definitions of _PFN_BITS, OBJ_INDEX_BITS
and OBJ_INDEX_MASK from zsmalloc-main.c to zsmalloc_int.h

They will be needed to determine ZS_MIN_ALLOC_SIZE in the next
patch

staging: zsmalloc: add ZS_MAX_PAGES_PER_ZSPAGE

This patch moves where max_zspage_order is declared and
changes its meaning.  "Order" typically implies 2^order
of something; however, it is currently being used as the
"maximum number of single pages in a zspage".  To add clarity,
ZS_MAX_ZSPAGE_ORDER is now used to calculate ZS_MAX_PAGES_PER_ZSPAGE,
which is 2^ZS_MAX_ZSPAGE_ORDER and is the upper bound on the number
of pages in a zspage.

staging: zsmalloc: calculate MAX_PHYSMEM_BITS if not defined

This patch provides a way to determine or "set a
reasonable value for" MAX_PHYSMEM_BITS in the case that
it is not defined (i.e. !SPARSEMEM)

staging: zsmalloc: change ZS_MIN_ALLOC_SIZE

This patch ensures that the value of ZS_MIN_ALLOC_SIZE, for the
PAGE_SIZE and MAX_PHYSMEM_BITS on the system, allows for all
possible object ids in the lowest storage class to be encoded
in the object handle.
