Yeah, yeah. I know Linus beat me to it ... I'm just "fashionably late".
--------------------------------
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.

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.

Again, correction, I get a tons of these even without the NVidia driver
module, so that's not the problem.
This problem is still pretty live unfortunately. Fixed in the new patchset ?
The problem doesn't seems fatal and the machine doesn't crash hard, but it's
still a bug.
Thanks

OK, this looks like the exit speedup stuff, which is removed in 63-mjb2,
could you retry with that?
