Subject2.5.59-mjb1 (scalability / NUMA patchset)
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.

http://www.aracnet.com/~fletch/linux/2.5.59/patch-2.5.59-mjb1.bz2

Since 2.5.58-mjb2 (~ = changed, + = added, - = dropped)

Notes:
Lots of good stuff merged up with Linus. x440 distcontigmem seems to have
problems in some circumstances, but APCI should work in this release.
