-Subject: [PATCH] i965/gen4: Fix GPU hangs since the program streaming change.
-
-This was tricky. We were doing a use-before-initialize of
-grf_reg_count, but the value usually got overwritten anyway -- when we
-didn't have to do a relocation (typical), or on gen5 when we didn't
-have relocations at all.

-Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
-(cherry picked from commit d03fdc4cdefdfdc5b59547945704c6037a5061c7)
