yeah. I'd too suggest to call it prefetch_stack(), and not make it a
macro & hook but something defined on all arches, with for now only ia64
having any real code in the inline function.

i'm wondering, is the switch_stack at the same/similar place as
next->thread_info? If yes then we could simply do a
prefetch(next->thread_info).
