sys/vm vm_map.c vm_map.h
Log:
o Add vm_map_unwire() for unwiring contiguous regions of either kernel
or user vm_maps. In accordance with the standards for munlock(2),
and in contrast to vm_map_user_pageable(), this implementation does not
allow holes in the specified region. This implementation uses the
"in transition" flag described below.
o Introduce a new flag, "in transition," to the vm_map_entry.
Eventually, vm_map_delete() and vm_map_simplify_entry() will respect
this flag by deallocating in-transition vm_map_entrys, allowing
the vm_map lock to be safely released in vm_map_unwire() and (the
forthcoming) vm_map_wire().
o Modify vm_map_simplify_entry() to respect the in-transition flag.
