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

Hi Paul,

Today's linux-next merge of the rcu tree got a conflict in
include/linux/sched.h between commit 907aed48f65e ("mm: allow PF_MEMALLOC
from softirq context") from Linus' tree and commit 46fc4e7c01b7 ("rcu:
Switch task's syscall hooks on context switch") from the rcu tree.

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