Please make tests your top priority. Without tests, I am not going to spend any
time reviewing this series, or any other hardware enabling series[*]. I don't
expect KVM specific tests for everything, i.e. it's ok to to rely things like
running VMs that utilize LAM and/or running LAM selftests in the guest, but I do
want a reasonably thorough explanation of how all the test pieces fit together to
validate KVM's implementation.
