Subject2.5.59-mjb2 (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-mjb2.bz2

Since 2.5.59-mjb1 (~ = changed, + = added, - = dropped)

Notes:
Added frlock xtime patches, cyclone timer fixes, sched stats.
I have new code for 4K stacks, but haven't applied it yet (next release).

+ schedstat Rick Lindsley
