Merge tag 'kvm-x86-coco-7.3' of https://github.com/kvm-x86/linux into HEAD
KVM guest_memfd and x86 CoCo changes for 7.3
- Forcefully invalidate SNP VMSA pages if their backing guest_memfd page is
zapped/invalidated, e.g. due to a PUNCH_HOLE in response to a Page-State
Change request.
- Rework the so called "prepare" and "invalidate" guest_memfd hooks to prepare
for in-place private<=>shared conversion, and clean up a few warts along the
way.
