Here is a patch that replaces all occurrences of dst_pmtu in the TCP
stack.  As a result we no longer need ext2_header_len.

This has a nice synergetic effect with Arnaldo's latest change to
linux/tcp.h :)

I'll be removing other users of dst->path/dst_pmtu next.

There is another bug in xfrm_bundle_ok where I forgot to
check the validity of xdst->route.  In fact, the check
on dst->path isn't strong enough either.  For IPv6 entries,
dst->path->obsolete is always negative until you call
ipv6_dst_check.  So we really need to do that here.

Here's the patch to fix those two problems.  Yes I know
my dst_check implementation is lame.  I'll come back and
fix up all the dst_check functions by moving their dst_release
calls out.  It proves that you were right in that IPv6 dst
leak thread :)

For the metrics other than MTU, we should also be getting it from
the top dst as opposed to the bottom dst.  With this change, the
user is able to manipulate values such as advmss for individual
hosts behind a remote IPsec gateway.

Let's also fix IPsec PMTU storage.  When we get an MTU update for an
xfrm_dst, it should be done to the top dst, not the bottom dst.

For example, when we get a need-to-frag message for host C behind
a our IPsec peer B, we should be updating the dst entry for C and
not B as we do now.

I've removed the boundary checks since the same checks are done
in ipv[46]/route.c already.

There was a lot of fun in laying the foundations.  Now it's time
to start using it.

This patch fixes the calculations in xfrm[46]_output so that we don't
reject properly sized packets from the TCP stack.  The previous
calculation is wrong because the xfrm overhead is not constant.

After this I'll start cleaning stuff up.  For example, tcp's
ext2_header_len and dst's path can both be removed.

Finally this is the patch that sets the MTU values of each xfrm_dst
and keeps it up-to-date.

To recap, at this point we've obtained accurate MTU values at each
xfrm_dst.  The next step would be to start using it as
dst_pmtu(xfrm_dst).

This patch adds a pointer to the route corresponding to the specific
flow over the SA of an xfrm_dst that's being used.

It also sets the next pointer of each xfrm_dst to the one above it.
This allows to traverse the list upwards from the bottom.

This patch introduces the function xfrm_state_mtu which calculates
the MTU under a specific SA.  This function can be simplified once
we get rid all other uses of get_max_size as we can move the calculation
into the invidual SA type.

This patch does:
	- consolidate the three implementations of compat_sys_waitid
	  (some were called sys32_waitid).
	- adds sys_waitid syscall to ppc
	- adds sys_waitid and compat_sys_waitid syscalls to ppc64

I have left PARISC and MIPS to their own devices (by request).

Patch from Ben Dooks

This patch extends the s3c2410 serial driver to allow it
to use fclk and correctly determine the uart dividers. The
necessary defines are added to the serial headers as well.
Also modified is the header to point at the current
Simtec linux pages, as well as extend the copyright.
