This patch implements the pzone (pseudo zone). A pzone can be used
for reserving pages in a zone. Pzones are implemented by extending
the zone structure and act almost the same as the conventional zones;
we can specify pzones in a zonelist for __alloc_pages() and the vmscan
code works on pzones with few modifications.

Could you divide this *large* patch to several pieces ?
It looks you don't want to use functions based on zones, buddy-system, lru-list
etc..
I think what you want is just a hierarchical memory allocator.
Why do you modify zone and make codes complicated ?
Can your memory allocater be implimented like mempool or hugetlb ?
They are not so invasive.
