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

Hi Andrew,

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

Caused by commit 802d335c0f7f ("prctl: PR_SET_MM -- introduce
PR_SET_MM_MAP operation").

I have reverted that commit (and commit c2e04b241d40
("prctl-pr_set_mm-introduce-pr_set_mm_map-operation-v3-fix") that
follows it) for today.
