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

Hi all,

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

  include/linux/socket.h

between commits:

  06947f40e3e9 ("net: socket: add __sys_recvfrom() helper; remove in-kernel call to syscall")
  bd4053a762c6 ("net: socket: move check for forbid_cmsg_compat to __sys_...msg()")

from the syscalls tree and commit:

  d8d211a2a0c3 ("net: Make extern and export get_net_ns()")

from the net-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.

Cheers,
Stephen Rothwell
