Yes, I understand. I will send testable and mergeable patches when the 
dependencies are in, and until that this series is do-not-merge. But as 
reviews sometimes take a very long time, I think it's better to start 
sooner than later.

Is there a way to mark a series as "don't bother testing" for automated 
tools? RFC in the subject? I considered making this RFC, but I felt the 
patches themselves are not RFC quality. I've also seen DNI 
(do-not-integrate) used somewhere, but I'm not sure that's universally 
understood.
