In HVM domains (or to be exact, when XENFEAT_auto_translated_physmap is
enabled) it is not valid to request the hypervisor set up a grant
mapping using PFNs referring to valid pages.  The balloon driver
provides alloc_xenballooned_pages to obtain pages without valid PFNs
suitable for grant mappings; use this function when allocating pages for
grant mappings.

This has been tested with a PV domain using block and network devices
exported by an HVM domain.
