How am I supposed to guess what this series is about? The rule is simple: you send a series with two patches or more, you include a cover letter describing your changes, what they provide, and how they interact with each other. Here, all I see is a bunch of seemingly unrelated changes. I could spend the next 2 hours trying to reverse engineer it, but it is probably a lot quicker for you to write an actual cover letter and send it for everyone's benefit.
