Let's go with the horrible-hack for 2.6.23, then revert it and get this
new approach merged and stabilised over the next week or two?

I would prefer to not have horrible hacks even temporary

The changes that we are considering for 2.6.24 will result in a single
zonelist per zone that will filter the zoneslist in alloc_pages. This lead
to a performance improvement in the page allocator.

What you call a hack is doing the same for the special policy zonelist in
2.6.23 in order to be able to apply policies to the two highest zones. We
apply a limited portion of the changes for 2.6.24 to .23 to fix the
ZONE_MOVABLE issue.
