With a few tweaks (will respond to individual patches), pushed everything except
the "Defer" patches to to branch `for_paolo/6.1` at:
https://github.com/sean-jc/linux.git
Unless you hear otherwise, it will make its way to kvm/queue "soon".
Regarding the "defer" patches, your patches are ok (with one or two tweaks), but
there are existing bugs that I believe will interact poorly with using reprogram_pmi
more agressively. Nothing major, but I'd prefer to get everything squared away
before merging, and definitely want your input on my proposed fixes. I'll post
the patches shortly.
