I was planning on applying this for 6.14.  Should I still do that, or do you want
to take the bulk of the series through kvm/next, or maybe let it set in
kvm-coco-queue?  I can't think of any potential conflicts off the top of my head,
and the refactoring is really only useful for TDX.

Patch 1 should go in sooner than later though.
