- 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
