long term robustness for new ports/codedrops indicates that having a
common header in linux/ and making arches opt-in via Kconfig/whatever
makes life a lot easier for everyone

everything builds by default with the generic C versions and arches
dont have to go through and figure out all the fun little stub files
they need to straight copy from other architectures ... they only have
to care if they want to implement an optimized version
