Paolo,

Much later than expected, but here's the second set of fixes KVM/arm64 for 6.18. The core changes are mostly fixes for a bunch of recent regressions, plus a couple that address the way pKVM deals with untrusted data. The rest address a couple of selftests, and Oliver's new email address.

Please pull,

M.
