  Modified files:
    sys/vm               vm_glue.c vm_map.c 
  Log:
  Acquire a read lock on the map inside of vm_map_check_protection() rather
  than expecting the caller to do so.  This (1) eliminates duplicated code in
  kernacc() and useracc() and (2) fixes missing synchronization in munmap().
