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

Pull drm radeon fixes from Dave Airlie:
 "One core fix, but mostly radeon fixes for s/r and big endian UVD
  support, and a fix to stop the GPU being reset for no good reason, and
  crashing people's machines."

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon: update lockup tracking when scheduling in empty ring
  drm/prime: Honor requested file flags when exporting a buffer
  drm/radeon: fix UVD on big endian
  drm/radeon: fix write back suspend regression with uvd v2
  drm/radeon: do not try to uselessly update virtual memory pagetable
