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.

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon: switch back to the CP ring for VM PT updates
  drm/radeon: prevent crash in the ring space allocation
  drm/radeon: Calling object_unrefer() when creating fb failure
