Hi,

This patch set adds SP800-90B compliance to the Jitter RNG. The
SP800-90B patch is tested for more than half a year in user space
with the Jitter RNG version 2.2.0.

The full SP800-90B assessment of the Jitter RNG is provided at [1].

In addition, the DRBG implementation is updated to always be
reseeded from the Jitter RNG. To ensure the DRBG is reseeded within
an appropriate amount of time, the reseed threshold is lowered.
