Hi Andrew,
Today's linux-next merge of the akpm-current tree got a conflict in
mm/vmacache.c between commit 50f5aa8a9b24 ("mm: don't pointlessly use
BUG_ON() for sanity check") from Linus' tree and commit 8beba5473820
("mm,vmacache: add debug data") from the akpm-current tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
