[Mesa-dev] i965: No relocation support for GL

[Chris Wilson]

Not much has changed in the couple of years since last posting, just a
lot of rebasing.

Still the major open question is how much locking do individual contexts
require amongst a shared set - can we rely of the upper layer providing
sufficient serialisation around access to brw_context?

The 40% improvement for silly relocation microbenchmarks is still there.
