Merge tag 'pm+acpi-3.15-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

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"
