Merge tag 'kvm-x86-sev-6.17' of https://github.com/kvm-x86/linux into HEAD
KVM SEV cache maintenance changes for 6.17
- Drop a superfluous WBINVD (on all CPUs!) when destroying a VM.
- Use WBNOINVD instead of WBINVD when possible, for SEV cache maintenance,
e.g. to minimize collateral damage when reclaiming memory from an SEV guest.
- When reclaiming memory from an SEV guest, only do cache flushes on CPUs that
have ever run a vCPU for the guest, i.e. don't flush the caches for CPUs
that can't possibly have cache lines with dirty, encrypted data.
