    ARM: 7765/1: perf: Record the user-mode PC in the call chain.

    commit c5f927a6f62196226915f12194c9d0df4e2210d7 upstream.

    With this change, we no longer lose the innermost entry in the user-mode
    part of the call chain.  See also the x86 port, which includes the ip.

    It's possible to partially work around this problem by post-processing
    the data to use the PERF_SAMPLE_IP value, but this works only if the CPU
    wasn't in the kernel when the sample was taken.

    ext4: fix overflow when counting used blocks on 32-bit architectures

    commit 8af8eecc1331dbf5e8c662022272cf667e213da5 upstream.

    The arithmetics adding delalloc blocks to the number of used blocks in
    ext4_getattr() can easily overflow on 32-bit archs as we first multiply
    number of blocks by blocksize and then divide back by 512. Make the
    arithmetics more clever and also use proper type (unsigned long long
    instead of unsigned long).

    ocfs2: xattr: fix inlined xattr reflink

    commit ef962df057aaafd714f5c22ba3de1be459571fdf upstream.

    Inlined xattr shared free space of inode block with inlined data or data
    extent record, so the size of the later two should be adjusted when
    inlined xattr is enabled.  See ocfs2_xattr_ibody_init().  But this isn't
    done well when reflink.  For inode with inlined data, its max inlined
    data size is adjusted in ocfs2_duplicate_inline_data(), no problem.  But
    for inode with data extent record, its record count isn't adjusted.  Fix
    it, or data extent record and inlined xattr may overwrite each other,
    then cause data corruption or xattr failure.

    One panic caused by this bug in our test environment is the following:

    handler to be installed before the EC _REG method is first invoked,
    add ec_skip_dsdt_scan() as HP Folio 13's callback to ec_dmi_table.

    genirq: Fix can_request_irq() for IRQs without an action

    commit 2779db8d37d4b542d9ca2575f5f178dbeaca6c86 upstream.

    Commit 02725e7471b8 ('genirq: Use irq_get/put functions'),
    inadvertently changed can_request_irq() to return 0 for IRQs that have
    no action.  This causes pcibios_lookup_irq() to select only IRQs that
    already have an action with IRQF_SHARED set, or to fail if there are
    none.  Change can_request_irq() to return 1 for IRQs that have no
    action (if the first two conditions are met).

    xen/time: remove blocked time accounting from xen "clockchip"

    commit 0b0c002c340e78173789f8afaa508070d838cf3d upstream.

    ... because the "clock_event_device framework" already accounts for idle
    time through the "event_handler" function pointer in
    xen_timer_interrupt().

    The patch is intended as the completion of [1]. It should fix the double
    idle times seen in PV guests' /proc/stat [2]. It should be orthogonal to
    stolen time accounting (the removed code seems to be isolated).

    The approach may be completely misguided.

    [1] https://lkml.org/lkml/2011/10/6/10
    [2] http://lists.xensource.com/archives/html/xen-devel/2010-08/msg01068.html

    John took the time to retest this patch on top of v3.10 and reported:
    "idle time is correctly incremented for pv and hvm for the normal
    case, nohz=off and nohz=idle." so lets put this patch in.

    jbd2: fix theoretical race in jbd2__journal_restart

    commit 39c04153fda8c32e85b51c96eb5511a326ad7609 upstream.

    Once we decrement transaction->t_updates, if this is the last handle
    holding the transaction from closing, and once we release the
    t_handle_lock spinlock, it's possible for the transaction to commit
    and be released.  In practice with normal kernels, this probably won't
    happen, since the commit happens in a separate kernel thread and it's
    unlikely this could all happen within the space of a few CPU cycles.

    On the other hand, with a real-time kernel, this could potentially
    happen, so save the tid found in transaction->t_tid before we release
    t_handle_lock.  It would require an insane configuration, such as one
    where the jbd2 thread was set to a very high real-time priority,
    perhaps because a high priority real-time thread is trying to read or
    write to a file system.  But some people who use real-time kernels
    have been known to do insane things, including controlling
    laser-wielding industrial robots.  :-)
