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.

Notes: I've left out some shiny new bits people have sent me because there
were a few things that were just broken. Fixing those up before
piling more on. Various floating fixes merged back into their main
elements to make maintaince easier (possible?)

On shutdown -h, I see the stack trace below before power
off. This is a Dell Poweredge 4400 with two 900MHz cpus.
I know that in the past, combining SMP and APM has been a
no-no -- don't know if that's what's going on.
I see this with 2.5.70-mm4, too, btw. At least it's very
similar: starts with close and produces a sleeping function
warning.
