+commit 8dee52997891108eec8e4df12dd02f3a060d9cb8
+Author: Chris Wilson <ch...@chris-wilson.co.uk>
+Date: Wed Nov 19 13:38:20 2014 +0000
+
+ sna: Add more checks and asserts for BLT capable bo
+
+ Before we use the BLT for core acceleration, double check that we can.
+ This should catch the case where we attempt to operate on SHM pixmaps
+ which do not meet the restrictions.

+Date: Tue Nov 18 08:37:25 2014 +0000
+
+ sna: Tweak alignment constraints on gen8 to allow BLT
+
+ The previous commits prevent us from using the BLT if the destination
+ address is misaligned. Honour that restriction when creating buffers as
+ well, so that they are always usuable by the BLT.
