Ok, I've gone through it and noticed a few things - mostly stuff that are
imo more complicated than necessary and that could be cut out.

Safe for the tlb flush wa I haven't cross-checked anything with Bspec, but
I don't expect any surprises there. I also haven't checked how good the
test coverage is (safe for suggesting that one test for execbuf failure
handling). But again, that's something which can be easily fixed.

The last thing I'm wondering is: How ready is mesa for this? I'd like to
merge this only when the mesa patches are ready to put it to good use.
Otherwise we run the decent risk of shipping broken code, which could end
up in a decent pain for userspace (worst case we have to add a new flag to
claim 'fixed context support').

Cheers, Daniel
