KVM: arm64: Expose unshare hypercall to the host Introduce an unshare hypercall which can be used to unmap memory from the hypervisor stage-1 in nVHE protected mode. This will be useful to update the EL2 ownership state of pages during guest teardown, and avoids keeping dangling mappings to unreferenced portions of memory.
