	sys/arch/xen/i386/pmap.c: revision 1.13
Apply patch from Jed Davis, posted to port-xen:
In pmap_remap_pages() new mappings are created (PG_RW|PG_M). When saving
a domain, the hypervisor will refuse to map the foreing pages RW.
As a temporary measure, retry the mapping read-only if PG_RW fails, so that
domain save will work. Also fix the PTP's wire_count if the MMU update
fails (prevent a kernel panic).
