  Merge tag 'kvmarm-fixes-6.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD (2024-10-06 03:59:22 -0400)

----------------------------------------------------------------
ARM64:

* 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

x86:

* Fix compilation with KVM_INTEL=KVM_AMD=n

* Fix disabling KVM_X86_QUIRK_SLOT_ZAP_ALL when shadow MMU is in use

Selftests:

* Fix compilation on non-x86 architectures

----------------------------------------------------------------
