Subject: orinoco driver causes *lots* of lockdep spew
Wow. Nearly 400 lines of debug spew, from a simple 'ifup eth1'.

ADDRCONF(NETDEV_UP): eth1: link is not ready
eth1: New link status: Disconnected (0002)

[ INFO: hard-safe -> hard-unsafe lock order detected ]
------------------------------------------------------
events/0/5 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
(af_callback_keys + sk->sk_family){-.--}, at: [<ffffffff802136b1>] sock_def_readable+0x19/0x6f
and this task is already holding:
(&priv->lock){++..}, at: [<ffffffff8824f70e>] orinoco_send_wevents+0x28/0x8b [orinoco]
which would create a new lock dependency:
(&priv->lock){++..} -> (af_callback_keys + sk->sk_family){-.--}
but this new dependency connects a hard-irq-safe lock:
(&priv->lock){++..}
... which became hard-irq-safe at:

[<ffffffff802609c4>] common_interrupt+0x64/0x65
to a hard-irq-unsafe lock:
