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

Hi Paul,

Today's linux-next merge of the rcu tree got a conflict in
kernel/rcu/rcutorture.c between commit d277d868dab6 ("rcu: Use MAX_NICE
to replace hardcoding of 19") from the tip tree (where this file is
called kernel/rcu/torture.c) and commit 5ccf60f23d33 ("rcutorture: Rename
PRINTK to TOROUT") from the rcu tree.

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

Cheers,
Stephen Rothwell                    sfr@...b.auug.org.au
