Subject2.5.71-mjb1
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/2.5.71/patch-2.5.71-mjb1.bz2

additional patches that can be applied if desired:

(these two form the qlogic feral driver)
