Merge tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random
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). * 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()
