If it's too late to get this into kvm/next, I'd say just ignore this pull request and I'll include them in the normal 7.3 selftests pull requests. I don't think there will be any cross-branch conflicts to juggle? But I've had these sitting in -next for a few weeks now, and getting them into kvm/next "now" would all but guarantee I won't end up having to play weird games with selftests patches. Thanks!
