[pull] radeon drm-fixes-3.8

[Marek Olšák]

This might be responsible for the bad r300g MSAA performance results
on Phoronix. I have no other explanation.

There is an optimization in r300g which forces the VRAM domain for
non-staging CB and DB only. Other than that, VRAM|GTT is the default
for all textures and GTT is the default for all buffers, so it's
pretty conservative.

For the future buffer-eviction heuristics, we should take into account
the actual resource usage - MSAA resources (and presumably scanout
resources as well) should stay in VRAM and shouldn't be evicted by
lesser resources unless the MSAA ones are idle for a very long time.
MSAA resources are usually pretty big (128 MB is needed for Full HD 8x
MSAA (CB+DB)), but that shouldn't stop the kernel from evicting as
many less-important resources as is necessary to reserve enough space
for MSAA.
