  Branch:      sys/kern  RELENG_2_1_0
               sys/vm    RELENG_2_1_0
  Modified:    sys/kern  init_main.c
               sys/vm    vm_glue.c vm_pageout.c
  Log:
  Retrofitted changes to add NO_SWAPPING option from -current (actually, it's
  the other way around - the changes in -current were based on these).
  The NO_SWAPPING option disables U-area paging (struct user & kernel stack)
  and can help improve performance in some special circumstances where a
  system has plenty of main memory and also has a lot of processes that are
  often in short waits (< 1 minute) but wake up frequently. Such is the
  case on a busy FTP archive like wcarchive. This option does not affect
  generic VM system paging.
