Why?

The only things which should be special about ZONE_NORMAL which I can think
of are:

a) All the early-allocated pinned memory is sitting there and

b) If you start an app which uses a lot of memory, its text pages will
probabyl be in ZONE_NORMAL while ZONE_DMA will contain just bss and
pagecache.
