  • Pull two powerpc fixes from Ben Herrenschmidt:
    "Here are a couple of fixes for 3.15. One from Anton fixes a nasty
    regression I introduced when trying to fix a loss of irq_work whose
    consequences is that we can completely lose timer interrupts on a
    CPU... not pretty.

    The other one is a change to our PCIe reset hook to use a firmware
    call instead of direct config space accesses to trigger a fundamental
    reset on the root port. This is necessary so that the FW gets a
    chance to disable the link down error monitoring, which would
    otherwise trip and cause subsequent fatal EEH error"

    "The first patch fixes a problem when we have a page count of 0 for

  • Pull xfs fixes from Dave Chinner:
    "Code inspection of the XFS error number sign translations found a
    bunch of issues, including returning incorrectly signed errors for
    some data integrity operations.

    These leak to userspace and result in applications not getting the
    errors correctly reported. Hence they need fixing sooner rather than
    later.

    A couple of the bugs are in data integrity operations, a couple more
    are in the new COLLAPSE_RANGE code. One of these came in through a
    recent ext4 merge and so I had to update the base tree to 3.15-rc5
    before fixing the issues"

  • Pull spi fixes from Mark Brown:
    "A few core fixes around outlying cases here, nothing that should

    !CONFIG_DMA, the actual meaningful change is much smaller.

    - Fix handling of unsupported dual and quad mode support on slave

    preventing regressions for drivers this is added.

  • Pull more cgroup fixes from Tejun Heo:
    "Three more patches to fix cgroup_freezer breakage due to the recent
    cgroup internal locking changes - an operation cgroup_freezer was
    using now requires sleepable context and cgroup_freezer was invoking
    that while holding a spin lock. cgroup_freezer was using an overly
    elaborate hierarchical locking scheme.

    While it's possible to convert the hierarchical spinlocks directly to
    mutexes, this patch simplifies the overall locking so that it uses a
    global mutex. This has the added benefit of avoiding iterating
    potentially huge number of tasks under a spinlock. While the patch is
    on the larger side in the devel cycle, the changes made are mostly
    straight-forward and the locking logic is a lot simpler afterwards"

  • Pull ACPI and power management fixes from Rafael Wysocki:
    "Still fixing regressions (partly by reverting commits that broke
    things for people), fixing other stable-candidate bugs and adding some
    blacklist entries for ACPI video and _OSI.

    Two ACPICA regression fixes (one recent and one for a 3.14 commit), a
    fix for an ACPI-related regression in TPM (introduced in 3.14), a
    revert of the ACPI AC driver conversion in 3.13 that went wrong for an
    unknown reason, two reverts of commits that attempted to remove an old
    user space interface in /proc and broke some utilities, in 3.13 too, a
    fix for a CPU hotplug bug in the ACPI processor driver (stable
    material), two (stable candidate) fixes for intel_pstate and a few new
    blacklist entries, mostly for systems that shipped with Windows 8.

    Specifics:

    - ACPICA fix for a stale pointer access introduced by a recent commit
    in the XSDT validation code from Lv Zheng.

    - ACPICA fix for the default value of the command line switch to
    favor 32-bit FADT addresses (in case there's a conflict between a
    64-bit and a 32-bit address). The previous default was that the
    32-bit version would take precedence and we tried to change it to
    the other way around and it didn't work. From Lv Zheng.

    - A TPM commit related to ACPI _DSM in 3.14 caused the driver to
    refuse to load if a specific _DSM was missing and that broke resume
    from system suspend on Chromebooks that require the TPM hardware to
    be restored to a working state during resume by the OS. Restore
    the old behavior to load the driver if the _DSM in question is not
    present, but prevent it from using the feature the _DSM is for.

    - ACPI AC driver conversion in 3.13 broke thermal management on at
    least one machine and has to be reverted. From Guenter Roeck.

    - Two reverts of 3.13 commits that attempted to remove the old ACPI
    battery interface in /proc, but turned out to break some utilities
    still using that interface. From Lan Tianyu.

    - ACPI processor driver fix to prevent acpi_processor_add() from
    modifying the CPU device's .offline field which leads to breakage
    if the initial online of the CPU fails. From Igor Mammedov.

    - Two intel_pstate fixes, one to take a BayTrail documentation update
    into account and one to avoid forcing the maximum P-state on init
    which causes CPU PM trouble on systems with P-states coordination
    when one of the CPU cores is initialized after an offline/online
    cycle triggered by user space. Both stable candidates, from Dirk
    Brandewie.

    - Fix for the ACPI video DMI blacklist entry for Dell Inspiron 7520
    from Aaron Lu.

    - Two new ACPI video blacklist entries for machines shipping with
    Win8 that need to use native backlight so that it can be controlled
    in a usual way (which doesn't work otherwise due bugs in the ACPI
    tables) from Hans de Goede.

  • When running send, if an inode only has extended reference items

    was incorrectly assuming the reference it found was of type
    BTRFS_INODE_REF_KEY due to use of the wrong key variable.
    This caused weird behaviour when using the found item has a regular

  • For inline data extent, we need to make its length aligned, otherwise,
    we can get a phantom extent map which confuses readpages() to return -EIO.

    This can be detected by xfstests/btrfs/035.

  • The new renameat2 syscall provides all the functionality of renameat
    with an additional flags argument, so make renameat optional so that
    future architectures can omit it without getting a warning.

    This patch doesn't affect existing architectures.

  • Add the renameat2 syscall to the generic syscall list, which is used by the
    following architectures: arc, arm64, c6x, hexagon, metag, openrisc, score,
    tile, unicore32.

  • Pull sound fixes from Takashi Iwai:
    "Unfortunately this update became bigger than previous pull requests,
    which is almost a pattern in rc5-6. But, the only obvious big changes
    are for the new Intel DSP ASoC drivers, so the impact must be fairly
    limited.

    Other than that, usual small fixes in various fields: HD-audio, ASoC
    core and ASoC fsl and codec drivers"

  • Pull parisc fixes from Helge Deller:
    "There are two patches in here:

    The first patch greatly improves latency and corrects the memory
    ordering in our light-weight atomic locking syscall.

    The second patch ratelimits printing of userspace segfaults in the
    same way as it's done on other platforms. This fixes a possible DOS
    on parisc since it prevents the syslog to grow too fast. For example,
    when the debian acl2 package was built on our debian buildd servers,
    this package produced lots of gigabytes in syslog in very short time
    and thus filled our harddisks, which then turned the server nearly
    completely unaccessible and unresponsive"

  • Pull Metag architecture and related fixes from James Hogan:
    "Mostly fixes for metag and parisc relating to upgrowing stacks.

    - Fix missing compiler barriers in metag memory barriers.
    - Fix BUG_ON on metag when RLIMIT_STACK hard limit is increased
    beyond safe value.
    - Make maximum stack size configurable. This reduces the default
    user stack size back to 80MB (especially on parisc after their
    removal of _STK_LIM_MAX override). This only affects metag and
    parisc.
    - Remove metag _STK_LIM_MAX override to match other arches and follow
    parisc, now that it is safe to do so (due to the BUG_ON fix
    mentioned above).
    - Finally now that both metag and parisc _STK_LIM_MAX overrides have
    been removed, it makes sense to remove _STK_LIM_MAX altogether"
