[Mesa-dev] [PATCH] r600g: Include SH and SMX when invalidating read caches

[Martin Andersson]

Not including the SH and SMX caches when invalidating read caches causes
random failures on some piglit tests when VA is enabled.

Since the failures are random, and there other problems also causing random
failures, it's hard to know exactly what tests were effected, but these
tests now consistently pass:

fast_color_clear/all-colors
fast_color_clear/redundant-clear
spec/!OpenGL 1.1/draw-pixels samples={2,4,6,8}
spec/!OpenGL 1.1/drawbuffer-modes
