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: (45 commits) drm/nv04: Fix set_operation software method. drm/nouveau: initialise DMA tracking parameters earlier drm/nouveau: use dma.max rather than pushbuf size for checking GET validity drm/nv04: differentiate between nv04/nv05 drm/nouveau: Fix null deref in nouveau_fence_emit due to deleted fence drm/nv50: prevent a possible ctxprog hang drm/nouveau: have ttm's fault handler called directly drm/nv50: restore correct cache1 get/put address on fifoctx load drm/nouveau: create function for "dealing" with gpu lockup drm/nouveau: remove unused nouveau_channel_idle() function drm/nouveau: fix handling of fbcon colours in 8bpp drm/nv04: Context switching fixes. drm/nouveau: Use the software object for fencing. drm/nouveau: Allocate a per-channel instance of NV_SW. drm/nv50: make the blocksize depend on vram size drm/nouveau: better alignment of bo sizes and use roundup instead of ALIGN drm/nouveau: Don't skip card take down on nv0x. drm/nouveau: Implement nv42-nv43 TV load detection. drm/nouveau: Clean up the nv17-nv4x load detection code a bit. drm/nv50: fix fillrect color ...
