Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux 

Pull drm fixes from Dave Airlie:
 "Daniel had some fixes queued up, that were delayed, the stolen memory
  ones and vga arbiter ones are quite useful, along with his usual bunch
  of stuff, nothing for HSW outputs yet.

  The one nouveau fix is for a regression I caused with the poweroff stuff"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: (30 commits)
