ISSUE DESCRIPTION
We have discovered a number of bugs in the code mapping and unmapping
grant references.
* If a grant is mapped with both the GNTMAP_device_map and
GNTMAP_host_map flags, but unmapped only with host_map, the device_map
portion remains but the page reference counts are lowered as though it
had been removed. This bug can be leveraged cause a page's reference
counts and type counts to fall to zero while retaining writeable
mappings to the page.
* Under some specific conditions, if a grant is mapped with both the
GNTMAP_device_map and GNTMAP_host_map flags, the operation may not
grab sufficient type counts. When the grant is then unmapped, the
type count wil
