You have a number of features that depend on several other series, and
as Krzysztof pointed out this is difficult to merge/review.. Could you
please create a "linux-next/master-ready" version of this series and
separate the changes for which the dependencies are unmet, putting them
at the end? This way we can take at least some of your diff.

If you still want review on them, you can also send them as [PATCH DNM]
or so
