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) ...
