    sys/vm               vm_map.c 
  Log:
   o Add vm_map_wire() for wiring contiguous regions of either kernel
     or user vm_maps.  This implementation has two key benefits when compared
     to vm_map_{user_,}pageable(): (1) it avoids a race condition through
     the use of "in-transition" vm_map entries and (2) it eliminates lock
     recursion on the vm_map.
  
  Note: there is still an error case that requires clean up.
