[PATCH] drm/ttm: pass buffer object for bind/unbind callback

From: Jerome Glisse ttm_tt is always associated with a buffer object, pass it in bind/unbind callback to make life easier for driver. Main objective is for driver supporting virtual address space. For such driver each buffer object can be several virtual address space but ttm is unaware of this.

[PATCH] drm/ttm: callback move_notify any time bo placement change

From: Jerome Glisse Previously we were calling back move_notify in error path when the bo is returned to it's original position or when destroy the bo. When destroying the bo set the new mem placement as NULL when calling back in the driver. Updating nouveau to deal with NULL placement properly.

ttm: merge ttm_backend & ttm_tt, introduce ttm dma allocator V7

Important fix to patch 14, fix accounting of ghost bo. When creating a ghost bo we don't account it, so set its acc_size to 0 so that when ghost is release we don't overfree. I wonder how i didn't run into this before. Patch are also at http://people.freedesktop.org/~glisse/ttmdma/ Cheers, Jero

[PATCH 02/14] drm/ttm: remove userspace backed ttm object support

[PATCH 03/14] drm/ttm: remove split btw highmen and lowmem page
