Hi Simon,

It's weird, in my akpm git log, I can find the following commit.

commit deed0460e01b3968f2cf46fb94851936535b7e0d

memory-hotplug: do not allocate pgdat if it was not freed when offline.

And there are 15 related patches following it. And above it, there are
some more related bugfix
from me and Andrew. They are all in -mm tree.

This is what I did:

$ git remote add next
http://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
$ git remote update next
$ git checkout -b next-akpm remotes/next/akpm

Please pull your tree and try again. :)

Thanks. :)
