  Modified files:
    sys/vm               vm_map.c 
  Log:
  Fix locking violations during page wiring:
  
   - vm map entries are not valid after the map has been unlocked.
  
   - An exclusive lock on the map is needed before calling
     vm_map_simplify_entry().
  
  Fix cleanup after page wiring failure to unwire all pages that had been
  successfully wired before the failure was detected.
