Subject: zoned vm counters: include per zone counters in /proc/vmstat
From: Christoph Lameter <clameter@xxxxxxx>
Add zoned counters to /proc/vmstat
This makes vmstat print counters from a combined array of zoned counters plus
the current page_state (which will be later be replaced by the event counter
patchset).
