The following series makes mapping a gfn from foreign domains more robust. Now
that xc_mem_paging_load() takes care of the page-in path, adjust also the
page-out path. This moves the pager out of the way and all places where a p2mt
check is done can now return -ENOENT right away.
Olaf
Changes:
xenpaging: extend xc_mem_paging_enable() to handle interface version
xenpaging: map gfn before nomination
xenpaging: add need_populate and paged_no_mfn checks
xenpaging: restore p2mt if gfn is needed before evict
xenpaging: improve evict error handling
