Ummmmm. Last I saw the idea was to simply have the fallback zonelist for allocations extend into other pgdats ... ;)

Both the current code and classzone will need some adjustments to work fine (as in: reasonably efficient) with NUMA.
If the classzone idea can be extended to NUMA with more readable (== maintainable) code than the standard zoned allocator, I'm all for having it integrated...
(I'm not sure if classzone will have many benefits in "normal" setups, but with NUMA I can see the idea giving a lot more performance benefits)
