Could you also have a look at my zone counters and event counter patchsets? This will split up the page statistics into important counters that we use (which are then per zone) and the ones that are only displayed via proc). It would really help to implement numa awareness in the VM if we could have per zone vm counters. The zone reclaim patchset would already benefit from it.
