Dave Airlie 017a27e7f5 Merge branch 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes 
Daniel writes:
Essentially just flush my -fixes queue before I head off to xdc.
- gen2 regression fixer, we've enabled the lvds stuff too late. Not
  causing any known issues, but this restores the sequence before a
  refactor that landed in 3.5, and lvds is a fickle beast. And seriously,
  who runs gen2 still ...
- downgrade a BUG to a WARN - we haven't root-caused/fixed the underlying
  issue yet, but this should help bug reporters quite a bit.
- properly disable hdmi audio - we've lost track of this, which resulted
  in the alsa driver again losing track of the unplug event.

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

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/
