linux-next: manual merge of the rcu tree with the tip tree

[Stephen Rothwell]

Hi Paul,

Today's linux-next merge of the rcu tree got a conflict in
kernel/rcutree.h between commit 62ab7072476a ("rcu: Use
smp_hotplug_thread facility for RCUs per-CPU kthread") from the tip tree
and commit daa5d37ff51b ("rcu: Prevent force_quiescent_state() memory
contention") from the rcu tree.

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