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/ipv4/ipmr_base.c

between commit:

  eddf016b9104 ("net: ipmr: fix unresolved entry dumps")

from the net tree and commit:

  e1cedae1ba6b ("ipmr: Refactor mr_rtm_dumproute")

from the net-next tree.

I fixed it up (I think - 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
