Andrew Morton 5a88a13d06 [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
  pages free     2365
        min      16

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