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.

Since 2.5.62-mjb1 (~ = changed, + = added, - = dropped)
Notes: This contains the new partially object based rmap code, that we're
very excited about ... peformance results to follow. It's still very early
days for this - *please* beat it up as much as possible, and see if you
can make it fall over. Seems pretty stable to me - kudos to Dave.
