[Karmic] Update to 2.6.31.12 Stable Kernel

[Surbhi Palande]

Hi All,

http://bugs.launchpad.net/bugs/510674

The 2.6.31.12 stable kernel has recently been released.

http://kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.31.12
http://kernel.org/pub/linux/kernel/v2.6/patch-2.6.31.12.bz2

The 2.6.31.12 upstream stable kernel brings in 14 patches. Two patches
from upstream 2.6.31.10 were excluded before in Ubuntu as they
introduced a regression. The fix for the regression is included in the
upstream 2.6.31.12 patch-set. I've applied and pushed these two patches
from upstream 2.6.31.10 and all the patches from upstream 2.6.31.12 to
my tree for review.

http://kernel.ubuntu.com/git?p=surbhi/ubuntu-karmic.git;a=shortlog;h=refs/heads/stable-2.6.31.12

The upstream process for stable tree updates is quite similar in scope
to the Ubuntu SRU process. e.g: each patch demonstrably fixes a bug and
is vetted by upstream either by originating directly from Linus' tree or
by being minimally backported from some patch in Linus' tree.

TEST CASE: TBD

The following bug might be resolved via patches from 2.6.31.12:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/453963

The 14 stable patches are as follows.  I've inlined my own review
comments (marked by #).

Thanks !

Warm Regards,
Surbhi.

    ipv6: skb_dst() can be NULL in ipv6_hop_jumbo()a

Closes the bug 8450 upstream which should have been completely fixed by
an older, related commit 483a47d2fe794328d29950fe00ce26dd405d9437. Like
the previous commit, this  commit disallows using the skb->dst before
its actually assigned.
