We've been through these pre-mmap games a few times, and always rejected
them, why is this any different?

Please use EXPORT_SYMBOL_GPL for all these crazy low-level exports.

To be homest I'd really like to see the whole thing as a patch series
instead of a pull request.  Very little seems to have gotten any
reviewed-by tags which makes me very suspicious.
