Paolo Bonzini 5b0d0d8542 KVM x86 MMU changes for 6.18
- Recover possible NX huge pages within the TDP MMU under read lock to
    reduce guest jitter when restoring NX huge pages.
 
  - Return -EAGAIN during prefault if userspace concurrently deletes/moves the
    relevant memslot to fix an issue where prefaulting could deadlock with the
    memslot update.
 
  - Don't retry in TDX's anti-zero-step mitigation if the target memslot is
    invalid, i.e. is being deleted or moved, to fix a deadlock scenario similar
    to the aforementioned prefaulting case.
