Merge branch 'drm-gem-update' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6 

* 'drm-gem-update' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6:
  drm/i915: Return error in i915_gem_set_to_gtt_domain if we're not in the GTT.
  drm/i915: Retry execbuffer pinning after clearing the GTT
  drm/i915: Move the execbuffer domain computations together
  drm/i915: Rename object_set_domain to object_set_to_gpu_domain
  drm/i915: Make a single set-to-cpu-domain path and use it wherever needed.
  drm/i915: Make a single set-to-gtt-domain path.
  drm/i915: If interrupted while setting object domains, still emit the flush.
  drm/i915: Move flushing list cleanup from flush request retire to request emit.
  drm/i915: Respect GM965/GM45 bit-17-instead-of-bit-11 option for swizzling.
