Pull xen fixes from Juergen Gross:

 - A series to fix a regression when running as a fully virtualized
   guest on an old Xen hypervisor not supporting PV interrupt callbacks
   for HVM guests.

 - A patch to add support to query Xen resource sizes (setting was
   possible already) from user mode.
