50bf46509f hwmon: (lm77) Do not preserve hysteresis when updating critical temp limit
Updating the hysteresis value when updating the critical temperature limit
was following the rule of 'least surprise'. However, it had the undesirable
side effect of changing the hysteresis for all other attributes, which
defeats the purpose of least surprise. In addition, it could result in
invalid hysteresis values if the resulting hysteresis was too large. In such
cases the resulting hysteresis ended up changed anyway, which again defeats
the purpose. So drop that code and document the new behavior.

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"

 errors correctly reported. Hence they need fixing sooner rather than later.

b2e3432af1 spi: Fixes for v3.15
A few core fixes around outlying cases here, nothing that should affect
 most users but useful fixes.  The diffstat is rather larger than one
 might hope due some simple code motion in the fix for !CONFIG_DMA, the
 actual meaningful change is much smaller.
 
  - Fix handling of unsupported dual and quad mode support on slave
    registration so that drivers that can degrade gracefully do so,
    preventing regressions for drivers this is added.
  - Fix build in !CONFIG_DMA cases following addition of generic DMA
    mapping support.
  - Fix error handling for queue creation which due to wider kernel
    changes can be triggered more easily.
  - A couple of driver specific fixes.

 "Three more patches to fix cgroup_freezer breakage due to the recent

  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"

478c7cf7a8 ACPI and power management fixes for 3.15-rc6
- 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.

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.

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

51a60253a5 Btrfs: send, fix incorrect ref access when using extrefs
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:
