i'd have to agree that updating asm/unistd.h fits better with existing
paradigm.  if we want to talk about converting *all cases* to Kconfig,
we can do it in a separate thread.  splitting the design between two
different files is simply confusing to everyone involved as they spend
their time going "well which way am *i* supposed to do it".
