This patch replaces most of the other uses of dst_pmtu with dst_mtu.
As far as I can tell these are either identical because dst->path == dst,
or they're a straightforward replacement of (the slightly incorrect)
dst_pmtu(dst) - dst->header_Len with dst_mtu(dst).

This patch uses dst_mtu instead of dst_pmtu in the various tunnel
implementations.  As it is they simply ignore the IPsec overhead.
This leads to bogus MTU values inside the tunnels.

This patch fixes the IPsec overhead handling in ip_append_data and
ip6_append_data.  As it is they assume that the IPsec overhead is
constant.  This is not true as with ESP the IPsec overhead will vary
as the MTU varies.

The result is that they may produce packets that will exceed the MTU
when ESP is used.  Had it taken the trailer_len into account, it would
have produced packets less than the real MTU.

By switching to dst_mtu we get the optimal result.

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

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

Otherwise ia64 and sparc64 explode with the new ptwalk
iterators.  The pgd level stuff does not handle virtual
address space holes (sparc64) and region based PGD indexing
(ia64) properly.  It only matters in functions like
clear_page_range() which potentially walk over more than
a single VMA worth of address space.
