Have you verified that all of these are __aligned(2)?

I haven't, but you should verify that you have in the
commit log.

btw: this use looks odd to me:

static int
bnad_set_mac_address(struct net_device *netdev, void *mac_addr)
{
	int err;
	struct bnad *bnad = netdev_priv(netdev);
	struct sockaddr *sa = (struct sockaddr *)mac_addr;
	unsigned long flags;

	spin_lock_irqsave(&bnad->bna_lock, flags);

	err = bnad_mac_addr_set_locked(bnad, sa->sa_data);

as it casts what seems to be a mac address to a
sockaddr and uses a different offset for sa->sa_data
than the mac_addr passed.

and the mac_addr as it's void doesn't need a cast.
