Linus Torvalds 818e607b57 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.

Pull random driver updates from Ted Ts'o:

(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).

* tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random:
  random: strengthen input validation for RNDADDTOENTCNT
  random: add backtracking protection to the CRNG
  random: make /dev/urandom scalable for silly userspace programs
  random: replace non-blocking pool with a Chacha20-based CRNG
  random: properly align get_random_int_hash
  random: add interrupt callback to VMBus IRQ handler
  random: print a warning for the first ten uninitialized random users
  random: initialize the non-blocking pool via add_hwgenerator_randomness()
