Adding Herbert. Here's a link to the series:

https://lore.kernel.org/kvm/88eef561-6fd8-a495-0d60-ff688070cc9e@redhat.com/T/#m2bbdd12452970d3bd7d0b1464c22bf2f0227a9f1

I'm not sure how you typically do the cross-tree stuff. Patch 8 has a
requirement on patches 1-7. The arch/x86/kvm/svm/sev.c file tends to have
more activity/changes than drivers/crypto/ccp/sev-dev.{c,h}, so it would
make sense to take it through the KVM tree. But I think you need to verify
that with Herbert.

Thanks,
Tom
