Re: [GIT PULL] ACPI and power management fixes for v3.15-rc6

[Rafael J. Wysocki]

Hi Linus,

Sorry for this last-minute update, but it's just turned out that
one of the new ACPI video blacklist entries was added overzealously
and added is a commit reverting it.

Please pull from

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm+acpi-3.15-rc6

to receive ACPI and power management fixes for v3.15-rc6
with top-most commit 658a0f4e661a6c07395de318a58f9058ba2faf8f

  Merge branch 'acpi-video'

on top of commit d6d211db37e75de2ddc3a4f979038c40df7cc79c

  Linux 3.15-rc5

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.

Thanks!
