Then:

 a) state this in the actual patch commit log.  Those need to be
    standalone and sufficiently describe what the patch is doing.
 b) do that in the actual series that makes use of them.  In fact
    for these kinds of changes the prep patch really seems like a bad
    idea to start with and it would be much easier to follow if the
    changes were done in the main patch.
