In an attempt to return a locked socket ax25_get_socket() was calling
lock_sock() with a spinlock held, bad idea.  Making matters worse it's
only user is running in bottom half context resulting in a potencial
attempt to sleep in bottom half context, so fix the locking there as well.

netlink_autobind has always set nlk_sk(sk)->groups to zero.  This is
unnecessary because sk_alloc already zeroes the entire structure.
Since a socket can only be bound once netlink_autobind doesn't need
to zero groups at all.

This had been safe until I added mc_list.  Now it is possible for
netlink_bind to race against netlink_autobind running on the same
socket on another CPU.  The result would be a socket that's on
mc_list with groups set to zero.  This socket will be left on the
list even after it is destroyed.

The fix is to remove the zeroing in netlink_autobind.

While replacing dst_pmtu in ip6_output I found this little gem.  In
ip6_forward we're not reloading the dst pointer after calling
xfrm6_route_forward.  So all subsequent dereferences of dst will
refer to its pre-IPsec value.

The solution is of course to refresh its value.

I'm now cleaning up all users of dst_pmtu with the aim of replacing
dst_pmtu with dst_mtu.  I'm going to start with the ones that actually
fix bugs.

This patch fixes the length calculation in icmp_send.  As it is
we're overestimating the space available by including the space
that would be used up by IPsec encapsulation.

IPv6 doesn't have this problem since its calculation is based
on 1280 instead of the PMTU.

When cleaning up the remaining users of dst_pmtu I noticed that
local_df wasn't being treated correctly in IPsec.  In fact, if
you socket's dst went over IPsec, local_df is essentailly ignored.

This patch fixes that.

AC97 Codec
This patch series adds support for the WM9713/WM9714 family of AC97
codecs. This family is different from 'standard' AC97 codecs in that the
default codec power state is 'off'. i.e. performing a register reset
will power the device down.

This patch also adds better support for larger single/double channel
enumerated mixer types.

This patch fixes a bug with the recently added printk-times feature.

In the case where a printk consists of only the log level (followed
subsequently by printks with more text for the same line), the printk-times
code doesn't correctly recognize the end of the string, and starts emitting
chars at the 0 byte at the end of the string.

The patch below fixes this problem.  It also adjusts the handling of
printed_len in the routine, which was affected by the printk-times feature.

This patch updates the sungem driver. I reworked all of the PM stuff, making it
less prone to races, probably simpler to read as well, and I no longer shut the
PHY down when the interface is down so that things like laptop-net no longer
die (the gain in power consumption was minimal, not worth the pain). I also
implemented basic WOL support.

There is still something I'm not totally happy with in the locking
(explained in the comment at the beginning), basically too much locking and a
couple of places with delays in locks. I will try to improve these later on.

It also adds a fix for a MAC reset issue when the receiver gets stuck.

This check is wrong, gcc optimizes it away:

                if ((len -= sizeof(pi)) > len)
			return -EINVAL;

This could be responsible for the BUG. If len is 2 or 3 and TUN_NO_PI
isn't set it underflows. alloc_skb() allocates len + 2, which is 0 or
1 byte. skb_reserve tries to reserve 2 bytes and things explode in
skb_put.
