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

[Stephen Rothwell]

Hi all,

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

  net/ipv4/udp.c

between commit:

  d894ba18d4e4 ("soreuseport: fix ordering for mixed v4/v6 sockets")

from the net tree and commit:

  ca065d0cf80f ("udp: no longer use SLAB_DESTROY_BY_RCU")

from the net-next tree.

I tried to fixed it up (see below).  Unfortunately,
hlist_add_tail_rcu() does not exist.  So instead I have reverted commit
d894ba18d4e4 ("soreuseport: fix ordering for mixed v4/v6 sockets") for
today.
