.. and there was a missing signoff in "KVM: SVM: Add module parameter
to enable SEV-SNP" so I ended up not using the pull request. But it
was still good to have it because it made it simpler to double check
what you tested vs. what I applied.

Also I have already received the full set of pull requests for
submaintainers, so I put it in kvm/next.  It's not impossible that it
ends up in the 6.10 merge window, so I might as well give it a week or
two in linux-next.
