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

Pull drm fixes from Dave Airlie:
 "A few regression fixes already, one for my own stupidity, and mgag200
  typo fix, vmwgfx fixes and ttm regression fixes, and a radeon register
  checker update for older cards to handle geom shaders"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon: allow geom rings to be setup on r600/r700 (v2)
  drm/mgag200,ast,cirrus: fix regression with drm_can_sleep conversion
  drm/ttm: Don't clear page metadata of imported sg pages
  drm/ttm: Fix TTM object open regression
  vmwgfx: Fix unitialized stack read in vmw_setup_otable_base
  drm/vmwgfx: Reemit context bindings when necessary v2
  drm/vmwgfx: Detect old user-space drivers and set up legacy emulation v2
  drm/vmwgfx: Emulate legacy shaders on guest-backed devices v2
  drm/vmwgfx: Fix legacy surface reference size copyback
  drm/vmwgfx: Fix SET_SHADER_CONST emulation on guest-backed devices
  drm/vmwgfx: Fix regression caused by "drm/ttm: make ttm reservation calls behave like reservation calls"
  drm/vmwgfx: Don't commit staged bindings if execbuf fails
  drm/mgag200: fix typo causing bw limits to be ignored on some chips
