[Intel-gfx] [GIT PULL] ACPI and power management fixes for v3.11-rc3

[Rafael J. Wysocki]

Hi Linus,

Please pull from the git repository at

  git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git pm+acpi-3.11-rc3

to receive ACPI and power management fixes for v3.11-rc3 with
top-most commit 8e5c2b776ae4c35f54547c017e0a943429f5748a

  Revert "ACPI / video / i915: No ACPI backlight if firmware expects Windows 8"

on top of commit 3b2f64d00c46e1e4e9bd0bb9bb12619adac27a4b

  Linux 3.11-rc2

These are just two fixes, a revert of the would-be backlight fix that didn't
work and an intel_pstate fix for two problems related to maximum P-state
selection.

Specifics:

- Revert of the ACPI video commit that I hoped would help fix
  backlight problems related to Windows 8 compatibility on some
  systems.  Unfortunately, it turned out to cause problems to happen
  too.

- Fix for two problems in intel_pstate, a possible failure to respond
  to a load change on a quiet system and a possible failure to select
  the highest available P-state on some systems.  From Dirk Brandewie.

Thanks!
