Subject: linux-next: build failure after merge of the mm tree

Hi all,

After merging the mm tree, today's linux-next build (powerpc64
allnoconfig) failed like this:

Presumably caused by commit

  f684ffc3ac9f ("powerpc/book3s64/radix: add support for vmemmap optimization for radix")

I have reverted that commit (and the following 2) for today.
