After some discussion, here's a second version of the patch I posted a
couple of weeks back to map grant references into HVM guests.  As
before, this is done by modifying the P2M map, but this time there's
no new hypercall to do it.  Instead, the existing GNTTABOP_map is
overloaded to perform a P2M mapping if called from a shadow mode
translate guest.  This matches the IA64 API.

The patch should apply cleanly to xen-unstable cset
