Merge branch kvm-arm64/mmu/vmid-cleanups into kvmarm-master/next
* kvm-arm64/mmu/vmid-cleanups:
: Cleanup the stage-2 configuration by providing a single helper,
: and tidy up some of the ordering requirements for the VMID
: allocator.
KVM: arm64: Upgrade VMID accesses to {READ,WRITE}_ONCE
KVM: arm64: Unify stage-2 programming behind __load_stage2()
KVM: arm64: Move kern_hyp_va() usage in __load_guest_stage2() into the callers
