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

Hi all,

Today's linux-next merge of the net-next tree got a conflict in
net/batman-adv/bat_iv_ogm.c between commit 7c24bbbeab41 ("batman-adv:
forward late OGMs from best next hop") from Linus' tree and commit
24a5deeb8a19 ("batman-adv: move ring_buffer helper functions in
bat_iv_ogm") from the net-next tree.

I fixed it up (as specified in your email (thanks) - see below) and can
carry the fix as necessary (no action is required).

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