Hi Andrew,

After merging the akpm-current tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit

33c3fc71c8cf ("mm: introduce idle page tracking")

from Linus' tree interacting with commit

3b1670dad702 ("page-flags: introduce page flags policies wrt compound pages")

from the akpm-current tree (and presumably others).

I have just dropped the akpm-current tree for today. I am sorry I
rushed you to put out a cleaned up mmotm yesterday :-(
