"- Regression fixer for an OOPS at boot when i915.ko is built-in and
  CONFIG_PM=n, introduce in 3.5 (patch from Hunt Xu)
- Regression fixer for occlusion query failures, the required w/a wasn't
  applied in all cases (thanks to Eric for tracking this on down).
- dmar vs. dma_buf imprt fix (Dave Airlie)
- 2 patches to fight down forcewake issues on snb. This is the stuff I've
  talked about 2 weeks ago already, it's a minefield. Investigation still
  going on, but afaict this is the best we have for now.
- a few minor things to keep coverty&compiler happy (Alan, Davendra,
  Stéphane)
- tons of hsw pci ids - this one is a bit late because internal approval
  sometimes takes a while, but ppl in charge finally agreed that world+dog
  already knows about ult and crw haswell variants ;-)

Wrt regressions I'm aware of:
- the power regression due to semaphores=1. Ben is running around with a
  killawatt, unfortunately we have a hard time reproducing this one. And
  this /shouldn't/ increase power usage. Ben has turned up a few odds bits
  though already.
- the lvds fix in 3.6-rc1 broke a backlight after lid close/open (but can
  be resurrected with a modeset cycle). I guess we anger the bios - I'm
  still looking into this one.
- gmbus broke edid reading on an odd-ball monitor, we need to fall-back.
  Due to vacation (both mine&the reporter's) this is stalling for a final
  patch and a tested-by on it. But issue is fully diagnosed."

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

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
