This is in use by a Xenstore sysctl and a Xenstore domctl. The sysctl is
hence already broken with the earlier series. Now the domctl is also being
screwed up. I don't think MGMT_HYPERCALLS really ought to extend to any
operations available to other than the core toolstack. That's the Xenstore
ones here, but also the ones used by qemu (whether run in Dom0 or a stubdom).
IOW I think there's a conceptual issue with this work which needs resolving
first.
