Pull kvm fixes from Paolo Bonzini:
 "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"

* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
  x86/reboot: emergency callbacks are now registered by common KVM code
  KVM: x86: leave kvm.ko out of the build if no vendor module is requested
  KVM: x86/mmu: fix KVM_X86_QUIRK_SLOT_ZAP_ALL for shadow MMU
  KVM: arm64: Fix kvm_has_feat*() handling of negative features
  KVM: selftests: Fix build on architectures other than x86_64
  KVM: arm64: Another reviewer reshuffle
  KVM: arm64: Constrain the host to the maximum shared SVE VL with pKVM
  KVM: arm64: Fix __pkvm_init_vcpu cptr_el2 error path
