There is not realistically going to be further work done here in the
4.12 timeframe.

The work so far has fixed a load of NULL pointer dereferences for blind
uses of d->vcpu[], but a number still remain for blind uses of
d->vcpu[0].  You can still crash Xen by issuing specific toolstack
hypercalls between createdomain and maxvcpus, but its now far harder
than in 4.11

Nor this.  There is a monitoring interaction issue I haven't got around
to fixing yet, and I've subsequently discovered that the way we inject
debug exceptions on VT-x is broken.  There is a specific passage in the
SDM which tells us not to do it the way we do, because otherwise we end
up with incorrect prioritisation of events when resuming the guest.
