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

Hi Dan,

Today's linux-next merge of the tmem tree got a conflict in mm/swapfile.c
between commit 43362a4977e3 ("oom: fix race while temporarily setting
current's oom_score_adj") from Linus' tree and commit 6ce5607c1edf ("mm:
frontswap: core swap subsystem hooks and headers") from the tmem tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.
