[GIT PULL] KVM: x86 pull requests for 7.3

Nothing super unusual is cycle.  I did manage to end up with two selftests pull
requests, appropriately named selftests and selftests2 in the spirt of KVM uAPI,
with a minor conflict between them.  I originally created a dedicated topic
branch for the new irq_test to isolate a dependency on the VFIO library, but
then realized I really wanted to use some of the new infrastructure APIs in
other tests.

Assuming you merge selftests before selftests2, the resolution I've been using is
to use the kvm_ prefixes pthread APIs (which assert success), but otherwise keep
the functional changes from "selftests".
