No, we haven't looked at doing that yet.  Part of that would be moving
things that are now in arch-specific area (like the <asm/dataplane.h>
header) to include/linux/, etc.; since this patch isn't ready for merge
yet, there are plenty of cleanups like that we'd want to do.  Probably the
next step is to figure out how to integrate what Tilera has done with the
nohz cpuset stuff that Frederic has so we retain the best of both worlds.
