* 'drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6:
  drm/radeon: Extended DDC Probing for Toshiba L300D Radeon Mobility X1100 HDMI-A Connector
  drm/ttm: ensure ttm for new node is bound before calling move_notify()
  drm/ttm: unbind ttm before destroying node in accel move cleanup
  drm/ttm: fix ttm_bo_add_ttm(user) failure path
  drm/radeon: Make vramlimit parameter actually work.
  drm/radeon: Explicitly print GTT/VRAM offsets on test failure.
  drm/radeon: Take IH ring into account for test size calculation.
  drm/radeon/alpha: Add Alpha support to Radeon DRM code
