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
include/net/scm.h between commit 83f1b4ba917d ("net: fix incorrect
credentials passing") from Linus' tree and commit 6b0ee8c036ec ("scm:
Stop passing struct cred") from the net-next tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).  I also applied the following merge fix patch (I am not
sure if this is correct, but it seems to be consistent):
