Subject: [ 49/64] drm/i915: Fix build failure

3.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lauri Kasanen <cand@....com>

commit 27b7c63a7c509d797c151e95a641e1d94d94bbd9 upstream.

ERROR: "__build_bug_on_failed" [drivers/gpu/drm/i915/i915.ko] undefined!

Originally reported at http://www.gossamer-threads.com/lists/linux/kernel/1631803
FDO bug #62775

This needs to be backported to both 3.7 and 3.8 stable trees. Doesn't apply straight,
but it's a quick change.
