The changes to common code reference an x86-specific variable. Also I don't
see how the changes make sense. Gnttab_transfer is deprecated so why would
you care about modifying that path?  The changes in page_alloc.c are
dependent on !hvm_domain(), but I thought the iommu changes were
specifically to support PCI passthru for HVM domains?
