Merge tag 'kvmarm-fixes-6.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 fixes for 6.12, take #1 - Fix pKVM error path on init, making sure we do not change critical system registers as we're about to fail - Make sure that the host's vector length is at capped by a value common to all CPUs - Fix kvm_has_feat*() handling of "negative" features, as the current code is pretty broken - Promote Joey to the status of official reviewer, while James steps down -- hopefully only temporarly
