Ah, you didn't even test this series, as it breaks the build
as-submitted.

{sigh}

In order for us to take this, I think you need to find someone else who
will validate your patch series _FIRST_ before submitting it to us.  And
I want their tested-by on them validating that it did actually work (if
for no other reason than to have someone else be willing to be
responsible if things go bad.)

Breaking our builds and forcing me to point out missing patches is not
how the stable kernel process works in any sane manner.
