    Pull random driver updates from Ted Ts'o:
     "A number of improvements for the /dev/random driver; the most
      important is the use of a ChaCha20-based CRNG for /dev/urandom, which
      is faster, more efficient, and easier to make scalable for
      silly/abusive userspace programs that want to read from /dev/urandom
      in a tight loop on NUMA systems.
    
      This set of patches also improves entropy gathering on VM's running on
      Microsoft Azure, and will take advantage of a hw random number
      generator (if present) to initialize the /dev/urandom pool"
    
    (It turns out that the random tree hadn't been in linux-next this time
    around, because it had been dropped earlier as being too quiet.  Oh
    well).
