4) An ordered zone list is probably the more natural mapping.

See my comments above about per zone/memblk.  And you reemphasize my point, how do we order the zone lists in such a way that a user of the API can easily know/find out what zone #5 is?

Could you explain how that problem is different from finding out
what memblk #5 is ... I don't see the difference?

Errm...  __memblk_to_node(5)

I"m not saying that we couldn't add a similar interface for zones... 
something along the lines of:
	__memblk_and_zone_to_flat_zone_number(5, DMA)
or some such.  It just isn't there now...

Also, right now, memblks map to nodes in a straightforward manner (1-1 
on NUMA-Q, the only architecture that has defined them).  It will likely 
look the same on most architectures, too.
