On Broadwell, g0.5 contains the "Scratch Space Pointer"; using OR puts some bits of that into "ignored" sections of our message header. While this doesn't hurt, it's also not terribly /useful/. Using MOV is sufficient to set the only interesting bits in this part of the message header. Signed-off-by: Kenneth Graunke <kenneth@whitecape.org> Reviewed-by: Eric Anholt <eric@anholt.net>
