When something, on receive, between a CHECKSUM_HW using
driver and the code validating skb->csum trims the head
of the packet we have to reset skb->ip_summed back to
CHECKSUM_NONE because this kind of change invalidates
the skb->csum value calculated by the driver.

Various spots handle this properly, but not all.  So
abstract these actions into helper routines in order
to avoid code duplication.

This is a second try to fix the long chain call lengths in netfilter.
The difference with the previous patch is that I got rid of the extra
argument. I somehow didn't see it could be done without using the 'int
*ret2' argument.

A comment on the number of arguments to nf_hook_slow: I don't think the
number of arguments should be decreased. For the bridge-nf code, f.e.,
the indev argument does not equal (*pskb)->dev (this is an answer to a
question of Rusty in the old thread).

A comment on the argument change of nf_hook_slow (sk_buff * to sk_buff
**) and the bad influence on tail call optimization possibilities. From
the discussion in the old thread it became clear that no tail call is
generated for the current code. So, I don't see why this is a reason not
to accept the patch. Furthermore, if gcc ever would become able of doing
the current code with a tail call, it should be very easy to change the
code back to the original. In the meantime, I think this patch is the
best known solution.

I'm oopsing on shutdown on a machine that has a Via Rhine adapter in it:

Unable to handle kernel paging request at virtual address e0803003

Seems like it is the ioread8 in:

        /* Hit power state D3 (sleep) */
        iowrite8(ioread8(ioaddr + StickyHW) | 0x03, ioaddr + StickyHW);

that fails. StickyHW is 0x83. lspci says:

0000:00:07.0 Ethernet controller: VIA Technologies, Inc. VT86C100A [Rhine] (rev 06)
        Flags: bus master, medium devsel, latency 32, IRQ 18
        I/O ports at ec00 [size=128]
        Memory at dfffff80 (32-bit, non-prefetchable) [size=128]

In other words, it's trying to read outside of the I/O range (0x80),
which matches the fauling address.

I'm guessing my chip revision doesn't support WOL, it's a crappy noname
card.

It does seem as if rhine_power_init checks quirks for rqWOL before
touching any registers. Should rhine_shutdown do the same? Proposed
patch below, which resolves the problem on my system.

Fix bug #4223.

OK, this happened because we got preempted before sis900_mii_probe
finished setting the sis_priv->mii.  Theoretically this can happen
with SMP as well but I suppose the number of SMP machines with sis900
is fairly small.

Anyway, the fix is to make sure that sis900_mii_probe is done before
the device can be opened.  This patch does it by moving the setup
before register_netdevice.

Since the netdev name is not available before register_netdev, I've
changed the relevant printk's to use pci_name instead.  Note that
one of those printk's may be called after register_netdev as well.

If further finer grained locking is needed, we can add a lock to the sysdev_class to
lock the class drivers list.  But if you do that, remember the global list also is still
there and needs to be protected.  That's why I went with a simple lock for everything.

The attached patch makes read/write semaphores use interrupt disabling
spinlocks in the slow path, thus rendering the up functions and trylock
functions available for use in interrupt context.  This matches the
regular semaphore behaviour.

I've assumed that the normal down functions must be called with interrupts
enabled (since they might schedule), and used the irq-disabling spinlock
variants that don't save the flags.

Thanks for the patch.  The original patch leaves the prototype for
aoechr_hdump in aoe.h, but since this function is just for debugging,
it seems better to just take both prototype and definition out.

Thanks.  With the changes below, it still will complain if it finds
