NUMA aware meminfo is one of the patches you have sitting in your tree. I haven't got around to the NUMA-sim yet ... maybe after Halloween when management stop asking me to get other bits of code in before the freeze ;-)

Ah, but what does a balance_classzone do on a NUMA box? Once you've finished rototilling the code you're looking at, I think we might have a better clue what it's supposed to do, at least ...
