+Subject: [PATCH] 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 ea7b1dd44867e9cd6bac67e7c9fc3f128b5b255c
+Author: Daniel Vetter <daniel.vetter at 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.
