Linus Torvalds 0f74665025 ACPI and power management fixes for 3.11-rc3 
- 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.

Pull ACPI and power management fixes from Rafael Wysocki:
 "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.

************************************************************

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).

The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:

    1. The DRM provides synchronized access to the graphics hardware via
       the use of an optimized two-tiered lock.

    2. The DRM enforces the DRI security policy for access to the graphics
       hardware by only allowing authenticated X11 clients access to
       restricted regions of memory.

    3. The DRM provides a generic DMA engine, complete with multiple
       queues and the ability to detect the need for an OpenGL context
       switch.

    4. The DRM is extensible via the use of small device-specific modules
       that rely extensively on the API exported by the DRM module.


Documentation on the DRI is available from:
    http://dri.freedesktop.org/wiki/Documentation
    http://sourceforge.net/project/showfiles.php?group_id=387
    http://dri.sourceforge.net/doc/
