NAK for the CS part (but I think that was just as prove of concept anyway).
Dave's sync object implementation is already done for this, the problem
is that isn't merged yet into amd-staging-4.12 (but should be in 4-13).
The VM part looks similar to what I had in mind, but we should base this
on Dave's sync_obj stuff as well.
Regards,
Christian.
