From -current NOTES (don't have 4.9 arround):
Disable swapping of upages and stack pages.  This option removes all
code which actually performs swapping, so it's not possible to turn
it back on at run-time.
This is sometimes usable for systems which don't have any swap space
(see also sysctls "vm.defer_swapspace_pageouts" and

options        NO_SWAPPING

But I think I used exactly that option when I did my embedded BSD more than 
one year ago.
