Doesn't even come close to applying to v3.0.18

That patch would only apply properly if the IB code is using the
dst_get_neighbour() interface, which doesn't even exist in v3.0.18

>>ipv4: fix lockdep splat in rt_cache_seq_show

Patch also does not apply, and for the same reason as the IB patch.

dst_get_neighbour() doesn't exist in v3.0.18, and therefore this code
being patched doesn't make use of it.

>>commit f7e57044eeb1841847c24aa06766c8290c202583
>>sch_teql: fix lockdep splat

I'm not even going to try applying this one, it's going to have the
same issue as the previous two.

The patch mentioned by commit 218fa90f072e4aeff9003d57e390857f4f35513e
("ipv4: fix lockdep splat in rt_cache_seq_show") is not in the v3.0.x
tree, and it's a prerequisite for the rt_cache_seq_show() change
being even necessary.

In all, I think this request is invalid.

You're asking me to submit patches to -stable which don't apply
even remotely, and whose dependencies haven't even been applied
to the tree.
