KVM: arm64: Allow userspace to limit NV support to nVHE
NV is hard. No kidding.
In order to make things simpler, we have established that NV would
support two mutually exclusive configurations:
- VHE-only, and supporting recursive virtualisation
- nVHE-only, and not supporting recursive virtualisation
For that purpose, introduce a new vcpu feature flag that denotes
the second configuration. We use this flag to limit the idregs
further.
