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.

additional patches that can be applied if desired:
(these three form the qlogic feral driver)

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.72/2.5.72-mm1/broken-out/isp-remove-pci_detect.patch
Since 2.5.72-mjb1 (~ = changed, + = added, - = dropped)
Notes: I applied lots of patches which affect similar areas. They all went on
without any problems. That's a worse omen than waking up in a pentagram
full of black candles ... chances I haven't managed to screw something up are
minimal. Go ahead, break it. Make my day.
