/dev/random Seeing Improvements For Linux 4.8

Yet another early pull request to talk about for the Linux 4.8 kernel are improvements to /dev/random.

Ted Ts'o submitted improvements today to the /dev/random driver for Linux 4.8. The improvements include using the ChaCha20-based CRNG for /dev/urandom as being faster, more efficient, and offer greater scalability.

The "random" improvements for Linux 4.8 also enhance the collection of entropy on VMs running Microsoft Azure by being able to take advantage of hardware random number generators where available.

More details on these /dev/random improvements here.
