Yeah, I know I'm "fashionably late", but I wanted to clear down some
stuff before porting to 2.5.55. Will do that tommorow.

The patchset contains mainly scalability and NUMA stuff, and anything
else that stops things from irritating me. It's meant to be pretty stable,
not so much a testing ground for new stuff.

I'd be very interested in feedback from anyone willing to test on any platform, however large or small.
