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

* 'drm-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: (50 commits)
  drm: include kernel list header file in hashtab header
  drm: Export hash table functionality.
  drm: Split out the mm declarations in a separate header. Add atomic operations.
  drm/radeon: add support for RV790.
  drm/radeon: add rv740 drm support.
  drm_calloc_large: check right size, check integer overflow, use GFP_ZERO
  drm: Eliminate magic I2C frobbing when reading EDID
  drm/i915: duplicate desired mode for use by fbcon.
  drm/via: vfree() no need checking before calling it
  drm: Replace DRM_DEBUG with DRM_DEBUG_DRIVER in i915 driver
  drm: Replace DRM_DEBUG with DRM_DEBUG_MODE in drm_mode
  drm/i915: Replace DRM_DEBUG with DRM_DEBUG_KMS in intel_sdvo
  drm/i915: replace DRM_DEBUG with DRM_DEBUG_KMS in intel_lvds
  drm: add separate drm debugging levels
  radeon: remove _DRM_DRIVER from the preadded sarea map
  drm: don't associate _DRM_DRIVER maps with a master
  drm: simplify kcalloc() call to kzalloc().
  intelfb: fix spelling of "CLOCK"
  drm: fix LOCK_TEST_WITH_RETURN macro
  drm/i915: Hook connector to encoder during load detection (fixes tv/vga detect)
