The genl_ops don't need to be written by anyone and thus can be moved in a
ro memory range.

batman-adv: Remove unnecessary lockdep in batadv_mcast_mla_list_free
batadv_mcast_mla_list_free() just frees some leftovers of a local feast
in batadv_mcast_mla_update(). No lockdep needed as it has nothing to do
with bat_priv->mcast.mla_list.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Mostly simple overlapping changes.
For example, David Ahern's adjacency list revamp in 'net-next'
conflicted with an adjacency list traversal bug fix in 'net'.

batman-adv: fix splat on disabling an interface
As long as there is still a reference for a hard interface held, there might
still be a forwarding packet relying on its attributes.
Therefore avoid setting hard_iface->soft_iface to NULL when disabling a hard
interface.
This fixes the following, potential splat:
batman_adv: bat0: Interface deactivated: eth1
batman_adv: bat0: Removing interface: eth1
cgroup: new mount options do not match the existing superblock, will be ignored
batman_adv: bat0: Interface deactivated: eth3
batman_adv: bat0: Removing interface: eth3

---[ end trace 647f9f325123dc05 ]---
What happened here is, that there was still a forw_packet (here: a BATMAN IV
OGM) in the queue of eth3 with the forw_packet->if_incoming set to eth1 and the
forw_packet->if_outgoing set to eth3.
When eth3 is to be deactivated and removed, then this thread waits for the
forw_packet queued on eth3 to finish. Because eth1 was deactivated and removed
earlier and by that had forw_packet->if_incoming->soft_iface, set to NULL, the
splat when trying to send/flush the OGM on eth3 occures.
