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

Pull drm fixes from Dave Airlie:
 "All fairly small: radeon stability and a panic path fix.

  Mostly radeon fixes, suspend/resume fix, stability on the CIK
  chipsets, along with a locking check avoidance patch for panic times
  regression"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon: use the CP DMA on CIK
  drm/radeon: sync page table updates
  drm/radeon: fix vm buffer size estimation
  drm/crtc-helper: skip locking checks in panicking path
  drm/radeon/dpm: resume fixes for some systems
