[Mesa-dev] [PATCH 0/5] i965/hsw: Use L3 with MOCS

[Chad Versace]

Nothing was landing in the L3 cache because we neglected to set the MOCS L3
bit. This fixes that and puts a bunch of stuff into L3.

Improves Xonotic 1920x1080 by +5.68% on Haswell Mobile GT2.
No Piglit regressions.

This series depends on Ken's recent patches and lives on my hsw-mocs-l3-v04 branc.
