Matt, sounds like you're volunteering? :)

>From my understanding, the roadmap looks something like:

1. Add checkpatch warning about IRQF_SAMPLE_RANDOM
2. Add any new add_*_randomness() functions (e.g. RTC and main clocks?
Serial or USB interrupts?)
3. Remove IRQF_SAMPLE_RANDOM macro (and checkpatch warning)
4. Add "pragmatic entropy accounting model"?
