linux-next: manual merge of the tip tree with Linus' tree

Hi all,

Today's linux-next merge of the tip tree got a conflict in
include/linux/mempolicy.h between commit 607ca46e97a1 ("UAPI: (Scripted)
Disintegrate include/linux") from Linus' tree and commits 6f98f92971e9
("mm/mpol: Make MPOL_LOCAL a real policy"), 84e3a981648d ("mm/mpol: Add
MPOL_MF_LAZY ..."), 0719b9688bfe ("mm/mpol: Add MPOL_MF_NOOP"),
4d58c795f691 ("mm/mpol: Check for misplaced page") and fa74ef9e42df
("sched/numa: Implement per task memory placement for 'big' processes")
from the tip tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

I also added this merge fix patch:

From: Stephen Rothwell <sfr@canb.auug.org.au>

Subject: [PATCH] mm/pol: fixups for UAPI include files split
