Entire series applied to the next branch!

On the first patch, I've fixed the minor issues pointed by Arnout:

    [Thomas: take into account comments made by Arnout:
      - Minor fixes in the documentation changes
      - Add @ before the tests done in the $(1)-update-config and
        $(1)-update-defconfig targets.]

Thanks a lot for your work on this topic!
