Please don't do this. I see nothing in these patches which requires that series, which makes this even more unnecessary. Since these are fairly trivial, I'm taking them and pushing to the ntb-next branch to give these more time to be tested (due to not being tested on the proper branch). I would really appreciate you testing the ntb-next branch as a sanity check.
