Bah, thought I'd caught all those... er, in fact I *had* caught those
but just sent the penultimate version. Definitely fixed now.

Ah yes. In fact I originally missed it out *completely* but then the
hmp bit didn't build when I tried to print it... :)

Should all be fixed in
https://git.infradead.org/users/dwmw2/qemu.git/commitdiff/5cf387fe307
which is part of the xenfv branch there; I'll repost soonish after
fixing a MemoryRegion refcount leak in kvm_xen_get_vcpu_info_hva().
It might even be posted without the [RFC] tag, at *least* as far as the
parts I've been posting already. We're still working on the PV backend
driver stuff which comes in the next phase.
Thanks again for the feedback.
