[PATCH][RFC]
fix ia64 grant_table destruction.
fix type count of grant mapped page for xen/ia64.
This patch is necessary to keep page_info.type_info
correctly. However I don't think that this patch is acceptable.
Another idea is to modify guest_physmap_remove_page() be aware
of grant table mapped page.
