We're seeing a number of build errors from this series, all of them
confusing.

I'll drop this version.  Please ensure that the various build errors
(including
https://lkml.kernel.org/r/8bf42bd2-1175-f26b-20b2-99b8c4a56aef@infradead.org)
are resolved after applying each patch, so we don't create bisection
holes.
