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

Pull drm fixes from Dave Airlie:
 "A bunch of fixes:
   - vmware memory corruption
   - ttm spinlock balance
   - cirrus/mgag200 work in the presence of efifb
  and finally Alex and Jerome managed to track down a magic set of bits
  that on certain rv740 and evergreen cards allow the correct use of the
  complete set of render backends, this makes the cards operate
  correctly in a number of scenarios we had issues in before, it also
  manages to boost speed on benchmarks my large amounts on these
  specific gpus."

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/edid: Make the header fixup threshold tunable
  drm/radeon: fix regression in UMS CS ioctl
  drm/vmwgfx: Fix nasty write past alloced memory area
  drm/ttm: Fix spinlock imbalance
  drm/radeon: fixup tiling group size and backendmap on r6xx-r9xx (v4)
  drm/radeon: fix HD6790, HD6570 backend programming
  drm/radeon: properly program gart on rv740, juniper, cypress, barts, hemlock
  drm/radeon: fix bank information in tiling config
  drm/mgag200: kick off conflicting framebuffers earlier.
  drm/cirrus: kick out conflicting framebuffers earlier
  cirrus: avoid crash if driver fails to load
