Subject: [ 63/68] drm/radeon/kms: set SX_MISC in the r6xx blit code (v2)

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

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

From: Marek Olšák <maraeo@...il.com>

commit cf00790dea6f210ddd01a6656da58c7c9a4ea0e4 upstream.

Mesa may set it to 1, causing all primitives to be killed.

v2: also update the r7xx code
