Working on a driver that needs them, but other modules might benefit as well.
The second version changes export symbols to GPL per Paul and Tejun's
suggestion.

Andrew, I don't have any percpu changes queued or scheduled for the
next merge window and I think it'd be easier if you can pick up this

Thanks a lot!
