Chris Wilson 901593f2bf drm: Only evict the blocks required to create the requested hole ... Avoid clobbering adjacent blocks if they happen to expire earlier and amalgamate together to form the requested hole. In passing this fixes a regression from commit ea7b1dd448 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Feb 18 17:59:12 2011 +0100 drm: mm: track free areas implicitly which swaps the end address for size (with a potential overflow) and effectively causes the eviction code to clobber almost all earlier buffers above the evictee. v2: Check the original hole not the adjusted as the coloring may confuse us when later searching for the overlapping nodes. Also make sure that we do apply the range restriction and color adjustment in the same order for both scanning, searching and insertion. v3: Send the version that was actually tested. Note that this seems to be ducttape of decent quality ot paper over some of our unbind related gpu hangs reported since 3.7. It is not fully effective though, and certainly doesn't fix the underlying bug.
