Doing it for the whole kernel probably doesn't buy you a whole lot more
than doing it a bit more selectively, which is what I was doing in
http://lkml.org/lkml/2006/8/24/212

I think Segher has been playing with it a bit recently, and confirms my
suspicion that combining kernel/ with arch/$ARCH/kernel, and mm/ with
arch/$ARCH/mm, is also a big win.

The GCC problems should mostly be fixed now, I think -- we just need to
have another go at doing the Kbuild side of it properly.
