In various test cases and workloads that put the system under a heavy load, we
can sometimes see errors with missed TLB invalidations. If we handle the TLB
completions directly from IRQ we can see a big improvement.
v4:
- Various tweaks. Big thing is to make sure we grab the fast_lock for the g2h
reservation when doing the CT send, which closes one big race with the CT
fast-path.
