      Linus Torvalds authored
      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"

      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

       "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"

       "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.
      
         - Two ACPI _OSI quirks for systems that need them to work correctly
           with Linux from Edward Lin and Hans de Goede"

      Btrfs: send, fix incorrect ref access when using extrefs · 51a60253
      Filipe Manana authored
      When running send, if an inode only has extended reference items
      associated to it and no regular references, send.c:get_first_ref()
      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
      reference, such as weird path string, and occasionally (when lucky)
      a crash:

      Btrfs: fix EIO on reading file after ioctl clone works on it · d3ecfcdf
      Liu Bo authored
      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

      This patch doesn't affect existing architectures.
