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:

Since 2.5.73-mjb1 (~ = changed, + = added, - = dropped)

Notes:
Small release, but upside_down may have large impact.
On the other hand, it's very cool, and solves various awkward problems.
See if you can break it ;-)
