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.
ftp://ftp.kernel.org/pub/linux/kernel/people/mbligh/2.5.68/patch-2.5.68-mjb 2.bz2 (may take a few minutes after sending this to appear)
