Jesse (or anyone else?), any objections to this patch as a superset of
yours?
No objections here. Of course, you'll have to rediff against the
current tree since that stuff has been merged for awhile now. On a
somewhat related note, Martin mentioned that he'd like to get rid of
memblks. I'm all for that too; they just seem to get in the way.

Here's an updated version against 2.6.1-rc1. Small comment fix (there
are actually up to (MAX_NUMNODES * MAX_NR_ZONES) possible zones total,
not log2(MAX_NUMNODES * MAX_NR_ZONES) as your comment stated. That is
the number of bits necessary to index every possible zone.
After this goes in, we (I) can convert a number of places that are doing
several pointer dereferences/arithmetic and other things to determine
which node/zone a page belongs to simply calling
page_nodenum()/page_zonenum().
Cheers!
