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

Hi all,

Today's linux-next merge of the bpf-next tree got a conflict in:

  include/net/ip_tunnels.h

between commit:

  bc9d003dc48c3 ("ip_tunnel: Preserve pointer const in ip_tunnel_info_opts")

from the net-next tree and commit:

  ac931d4cdec3d ("ipip,ip_tunnel,sit: Add FOU support for externally controlled ipip devices")

from the bpf-next tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
