Linus Torvalds 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
