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

Hi all,

Today's linux-next merge of the tip tree got conflicts in
include/linux/clockchips.h, kernel/time/tick-broadcast.c,
kernel/time/tick-common.c and kernel/time/tick-internal.h between
commit 01b9fdf7e540 ("tick: Move core only declarations and functions
to core") (and others) from the pm tree and commit 77e32c89a711
("clockevents: Manage device's state separately for the core") (and
others) from the tip tree.

I fixed it up (I *think* I may have figured it all out, but please
check - see below and teh final tree later) and can carry the fix as
necessary (no action is required).

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