And the point of having kvm_vcpu_* vs. kvm_write_* was exactly to not
having to hardcode the address space ID. If anything you could add a
__kvm_vcpu_write_* API that takes vcpu+as_id, but really I'd prefer to
keep kvm_get_running_vcpu() for now and then it can be refactored later.
There are already way too many memory r/w APIs...
