Fix const assignment/discard warnings in the ATM networking driver.
The lane2_assoc_ind() function needed its arguments changing to match changes
in the lane2_ops struct (patch 61c33e0129
"atm: use const where reasonable").

Without CONFIG_NET_NS, namespace is always &init_net.
Compiler will be able to omit namespace comparisons with this patch.

It happens that if a packet arrives in a VC between the call to open it on
the hardware and the call to change the backend to br2684, br2684_regvcc
processes the packet and oopses dereferencing skb->dev because it is
NULL before the call to br2684_push().

This reverts commit 65e4113684.
Unlike the other cases Pavel fixed, this case did not
setup a netdev->destructor of free_netdev, therefore this
change was not correct.

Both br2684_push and br2684_exit do so, but unregister_netdev()

Simply replace proc_create and further data assigned with proc_create_data.
proc_atm_dev_ops holds proper referrence.

If print_mac() is used inside of a pr_debug() the compiler
can't see that the call is redundant so still performs it
even of pr_debug() ends up being a nop.
So don't use print_mac() in such cases in hot code paths,
use MAC_FMT et al. instead.
As noted by Joe Perches, pr_debug() could be modified to
handle this better, but that is a change to an interface
used by the entire kernel and thus needs to be validated
carefully. This here is thus the less risky fix for
2.6.25

Introduce per-sock inlines: sock_net(), sock_net_set()
and per-inet_timewait_sock inlines: twsk_net(), twsk_net_set().
Without CONFIG_NET_NS, no namespace other than &init_net exists.
Let's explicitly define them to help compiler optimizations.

This is a callback registered to inet address notifier chain.
The check is useless as:
- ifa->ifa_dev is always != NULL
- similar checks are abscent in all other notifiers.

The iterator state->ns.neigh_sub_iter initialization is moved from

cat /proc/net/atm/arp causes the NULL pointer dereference in the
get_proc_net+0xc/0x3a. This happens as proc_get_net believes that the
parent proc dir entry contains struct net.
Fix this assumption for "net/atm" case.
The problem is introduced by the commit c0097b07abf5f92ab135d024dd41bd2aada1512f
from Eric W. Biederman/Daniel Lezcano.
