Linus Torvalds f19637e743 Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux 
Pull radeon fixes from Dave Airlie:
 "I got these late last week, the main chunks of these fix a rendering
  regression since 3.7, and the settle ones all fix the issue where we
  don't wait long enough for the memory controller to settle after
  turning it off which causes bad memory reads, they all fix real users
  bugs, and most of them are destined for stable.

  Can't remember if you had net connection on that island :-)"

I don't know if the "two tin-cans and a string" thing here on "that
island" can really be considered internet, but I guess I can pull
things.  Barely.

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

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
