[PATCH] /proc/zoneinfo: fix vm stats display
This early break prevents us from displaying info for the vm stats thresholds
if the zone doesn't have any pages in its per-cpu pagesets.
So my 800MB i386 box says:
Node 0, zone DMA

Just nuke all that search-for-the-first-non-empty-pageset code. Dunno why it
was there in the first place..
