Alan Cox 6bbee8e28a Add a new option, OBJPR_NOTMAPPED, to vm_object_page_remove(). Passing this ... option to vm_object_page_remove() asserts that the specified range of pages is not mapped, or more precisely that none of these pages have any managed mappings. Thus, vm_object_page_remove() need not call pmap_remove_all() on the pages. This change not only saves time by eliminating pointless calls to pmap_remove_all(), but it also eliminates an inconsistency in the use of pmap_remove_all() versus related functions, like pmap_remove_write(). It eliminates harmless but pointless calls to pmap_remove_all() that were being performed on PG_UNMANAGED pages. Update all of the existing assertions on pmap_remove_all() to reflect this change.
