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

Hi all,

Today's linux-next merge of the net-next tree got a conflict in
net/ipv6/ip6_tunnel.c between commit abb6013cca14 ("ipv6: fix the use of
pcpu_tstats in ip6_tunnel") from the net tree and commit 8f84985fec10
("net: unify the pcpu_tstats and br_cpu_netstats as one") from the
net-next tree.

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

Cheers,
