How to pull a single changeset from a child branch into a parent branch?

I have a linux-2.6 repo with two branches off of 2.6.13.

One branch (ben_v13) has just my own changes.
A second branch (work_v13) has the 2.6.13.5 patch, and I've also pulled
ben_v13 into it.

Now, I made a small change to work_v13, and I'd like to pull only
that changeset into ben_v13.  Is there a way to do that w/out
having to export and apply a patch?

Thanks,
Ben
