FYI, there are 4-5 minor conflicts with kvm-x86/next, and going off my memory, I
think the conflicts come from ~3 different topic branches.

Given that this is based on kvm/next, I assume it's destined for 6.9.  So maybe
rebase on kvm-x86/next for v3, and then I'll get my 6.9 pull requests sent for
the conflicting branches early next week so that this can land in a topic branch
that's based on kvm/next?
