We re-test once the mutex is acquired to make sure it's still true before doing the -modify-write part of the read-modify-write. Note that due to the maximum fifo depth being pretty deep, this is unlikely to improve harvesting performance yet. Approved by: markm Start the entropy device insecure/unblocked.

The only hardware source used at this point is the one inside the VIA C3 Nehemiah (Stepping 3 and above) CPU. More sources will be added in due course. Contributions welcome!
