xen: add xen_set_domain_pte()
Add xen_set_domain_pte() to allow setting a pte mapping a page from another domain. The common case is to map from DOMID_IO, the pseudo domain which owns all IO pages, but will also be used in the privcmd interface to map other domain pages. [ Impact: new Xen-internal API for cross-domain mappings ] Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
