[Patch:RFC] New zone ZONE_EASY_RECLAIM[2/5]

[Patch:RFC] New zone ZONE_EASY_RECLAIM[2/5]

[Yasunori Goto]

This defines new zone ZONE_EASY_RECLAIM.

Note:
  I found DMA32_ZONE is included in -mm tree.
  If one more new zone is created before/after my patch, 
  the zone number field in page->flags is not enough.
  My patch doesn't care about it yet.
