Please be more specific in your replies, no one will accept code that
"does stuff" and expecting a reviewer to spend time guessing or pulling
the information out of you is a sure way to get your patches ignored.

Exactly what kind of stuff are you talking about here and exactly which
problem are you solving.

Make your proprietary code work with the upstream kernel and you
shouldn't ever have to modify it.
