Move them into mm, drop these redundant definitions and instead
just select it on applicable platforms.

This makes sense and looks good. A series like this is a little tricky.
The latter patches change the contracts so it'd be easiest to run it
through my tree. We'd need to get explicit acks from each arch
maintainer to make sure they're fine with this.

Got it, I will resend without RFC and hope to get ACKs from related arch 
maintainers.

Thanks,
Dennis
