This patch is the minimal amount of code needed to support
wake-on-lan in platform mode properly (i.e. "ethtool -s eth0 wol g"
is sufficient, no additional magic needed) for me.
This is derived from David Brownells patch
(http://lists.laptop.org/pipermail/devel/2007-April/004691.html).
However I decided to move the hook into pci-acpi.c since the other
two pci hooks also live there and pci and acpi are the only users of
the platform_enable_wakeup-hook.
As a 'side-effect' this also makes wake on usb activity work for me
and I had to disable usb wakeup (which is enabled by default) using
the power/wakeup sysfs functionality ("echo disabled >
${sysfs_path_to_device}/power/wakeup").
(BTW I first thought the 'immediate reboot because of usb wake' effect is
caused by the optical mouse generating a wake event, but it rather
seems to be a problem with a flaky secondary usb host controller,
which sees a connected device where nothing is attached)

We currently don't signal the kernel we that this device can wake
the system. Call device_init_wakeup() to correct this.
Without this device_can_wakeup and device_may_wakeup will return
incorrect values.
Together with the minimized acpi wakeup patch (6/4 ;)), which will
follow in the next mail, this really makes wake-on-lan work for me
as expected (i.e. "ethtool -s eth0 wol g" is sufficient, no
additional magic needed).

The call to e1000_clean_tx_irq in e1000_netpoll can race with the call
to e1000_clean_tx_irq in e1000_clean. With a small bit of tweaking to
to netpoll_send_skb to simulate a system that was under extreme stress,
I was able to reproduce these concurrent calls. This can result in
multiple frees to the skbs on the tx ring buffer.
Dropping this call from e1000_netpoll should be fine since we can rely
on the calls in e1000_clean to do what is needed since napi will poll
the hardware just after calling poll_controller.

There is a missing "!" in a conditional statement which is causing entries to
be skipped when dumping the default IPv6 static label entries. This can be
demonstrated by running the following:
# netlabelctl unlbl add default address:::1 \
label:system_u:object_r:unlabeled_t:s0
# netlabelctl -p unlbl list
... you will notice that the entry for the IPv6 localhost address is not
displayed but does exist (works correctly, causes collisions when attempting
to add duplicate entries, etc.).

When an SKB cannot be chained to a session, the current code attempts
to "restore" its ip_summed field from lro_mgr->ip_summed. However,
lro_mgr->ip_summed does not hold the original value; in fact, we'd
better not touch skb->ip_summed since it is not modified by the code
in the path leading to a failure to chain it. Also use a cleaer
comment to the describe the ip_summed field of struct net_lro_mgr.

The problem is that while we work w/o the inet_frags.lock even
read-locked the secret rebuild timer may occur (on another CPU, since
BHs are still disabled in the inet_frag_find) and change the rnd seed
for ipv4/6 fragments.
It was caused by my patch fd9e63544c
([INET]: Omit double hash calculations in xxx_frag_intern) late
in the 2.6.24 kernel, so this should probably be queued to -stable.

I got a problem when I wanted to check if the kernel supports process
event connector, and It seems there's no way to do this check.
At best I can check if the kernel supports connector or not, by looking
into /proc/net/netlink, or maybe checking the return value of bind() to
see if it's ENOENT.
So it would be useful to add /proc/net/connector to list all supported
connectors:
# cat /proc/net/connector
Name ID
connector 4294967295:4294967295
cn_proc 1:1
w1 3:1
