* 'drm-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6:
  drm/radeon/kms: fix bo's fence association
  drm/radeon/kms: fix indirect buffer management V2
  drm/edid: Fix interlaced detailed timings to be frame size, not field.
  drm/vmwgfx: Use fb handover mechanism instead of stealth mode.
  drm/radeon/kms: use udelay for short delays
  drm/nouveau: Force TV encoder DPMS reinit after resume.
  drm/nouveau: use mutex for vbios lock
