The following commit has been merged in the master branch:
commit b3e0d3d7bab14f2544a3314bec53a23dc7dd2206
Merge: 3268e5cb494d8778a5a67a9fa2b1bdb0243b77ad 73796d8bf27372e26c2b79881947304c14c2d353
Author: David S. Miller <davem(a)davemloft.net>
Date: Thu Dec 17 22:08:28 2015 -0500
Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts:
drivers/net/geneve.c
Here we had an overlapping change, where in 'net' the extraneous stats
bump was being removed whilst in 'net-next' the final argument to
udp_tunnel6_xmit_skb() was being changed.
