Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Conflicts:
	net/ipv6/route.c

This deals with a merge conflict between the net-next addition of the
inetpeer network namespace ops, and Thomas Graf's bug fix in
2a0c451ade8e1783c5d453948289e4a978d417c9 which makes sure we don't
register /proc/net/ipv6_route before it is actually safe to do so.
