KVM: arm64: Unconditionally cross check hyp state Now that the hypervisor's state is stored in the hyp_vmemmap, we no longer need an expensive page-table walk to read it. This means we can now afford to cross check the hyp-state during all memory ownership transitions where the hyp is involved unconditionally, hence avoiding problems such as [1].
