1) checkout the top most commit of patch set (i.e. isn't needed for any other patches)
   (git fetch https://review.openstack.org/openstack/nova refs/changes/53/123553/3 && git checkout FETCH_HEAD)
2) checkout a new branch
   (git checkout -b "blah")
3) do an interactive rebase down to the commit before our changes. (you can do a 'git log' to find this)
   (git rebase -i fe2d5d2730b1ec798e3d41023eaa1599c9937f58)
4) change 'pick' to 'edit' for commits you want to edit
5) make needed changes to patch, add them (git add), then commit them (git commit --amend)
6) git rebase --continue and repeat 5 until you're done
