27d7ff46a3 [SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}
To clearly state the intent of copying to linear sk_buffs, _offset being a
overly long variant but interesting for the sake of saving some bytes.

da952315c9 [IPCOMP]: Fix truesize after decompression
The truesize check has uncovered the fact that we forgot to update truesize
after pskb_expand_head.  Unfortunately pskb_expand_head can't update it for
us because it's used in all sorts of different contexts, some of which would
not allow truesize to be updated by itself.

So the solution for now is to simply update it in IPComp.

This patch also changes skb_put to __skb_put since we've just expanded
tailroom by exactly that amount so we know it's there (but gcc does not).

364c6badde [NET]: Clean up skb_linearize
The linearisation operation doesn't need to be super-optimised.  So we can
replace __skb_linearize with __pskb_pull_tail which does the same thing but
is more general.

Also, most users of skb_linearize end up testing whether the skb is linear
or not so it helps to make skb_linearize do just that.

Some callers of skb_linearize also use it to copy cloned data, so it's
useful to have a new function skb_linearize_cow to copy the data if it's
either non-linear or cloned.

Last but not least, I've removed the gfp argument since nobody uses it
anymore.  If it's ever needed we can easily add it back.

Misc bugs fixed by this patch:

* via-velocity error handling (also, no SG => no frags)

31a4ab9302 [IPSEC] proto: Move transport mode input path into xfrm_mode_transport
Now that we have xfrm_mode objects we can move the transport mode specific
input decapsulation code into xfrm_mode_transport.  This removes duplicate
code as well as unnecessary header movement in case of tunnel mode SAs
since we will discard the original IP header immediately.

This also fixes a minor bug for transport-mode ESP where the IP payload
length is set to the correct value minus the header length (with extension
headers for IPv6).

Of course the other neat thing is that we no longer have to allocate
temporary buffers to hold the IP headers for ESP and IPComp.

6f91204225 [PATCH] for_each_possible_cpu: network codes
for_each_cpu() actually iterates across all possible CPUs.  We've had mistakes
in the past where people were using for_each_cpu() where they should have been
iterating across only online or present CPUs.  This is inefficient and
possibly buggy.

We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the
future.

This patch replaces for_each_cpu with for_each_possible_cpu under /net

e695633e21 [IPSEC]: Kill unused decap state argument
This patch removes the decap_state argument from the xfrm input hook.
Previously this function allowed the input hook to share state with
the post_input hook.  The latter has since been removed.

The only purpose for it now is to check the encap type.  However, it
is easier and better to move the encap type check to the generic
xfrm_rcv function.  This allows us to get rid of the decap state
argument altogether.

573dbd9596 [CRYPTO]: crypto_free_tfm() callers no longer need to check for NULL
Since the patch to add a NULL short-circuit to crypto_free_tfm() went in,
there's no longer any need for callers of that function to check for NULL.
This patch removes the redundant NULL checks and also a few similar checks
for NULL before calls to kfree() that I ran into while doing the
crypto_free_tfm bits.

I've succesfuly compile tested this patch, and a kernel with the patch 
applied boots and runs just fine.

When I posted the patch to LKML (and other lists/people on Cc) it drew the
following comments :

 J. Bruce Fields commented
  "I've no problem with the auth_gss or nfsv4 bits.--b."

 Sridhar Samudrala said
  "sctp change looks fine."

 Herbert Xu signed off on the patch.

So, I guess this is ready to be dropped into -mm and eventually mainline.

72cb6962a9 [IPSEC]: Add xfrm_init_state
This patch adds xfrm_init_state which is simply a wrapper that calls
xfrm_get_type and subsequently x->type->init_state.  It also gets rid
of the unused args argument.

Abstracting it out allows us to add common initialisation code, e.g.,
to set family-specific flags.

The add_time setting in xfrm_user.c was deleted because it's already
set by xfrm_state_alloc.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
