Merge tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random
Pull randomness updates from Ted Ts'o: "Cleanups and bug fixes to /dev/random, add a new getrandom(2) system call, which is a superset of OpenBSD's getentropy(2) call, for use with userspace crypto libraries such as LibreSSL. Also add the ability to have a kernel thread to pull entropy from hardware rng devices into /dev/random" * tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random: hwrng: Pass entropy to add_hwgenerator_randomness() in bits, not bytes random: limit the contribution of the hw rng to at most half random: introduce getrandom(2) system call hw_random: fix sparse warning (NULL vs 0 for pointer) random: use registers from interrupted code for CPU's w/o a cycle counter hwrng: add per-device entropy derating hwrng: create filler thread random: add_hwgenerator_randomness() for feeding entropy from devices random: use an improved fast_mix() function random: clean up interrupt entropy accounting for archs w/o cycle counters random: only update the last_pulled time if we actually transferred entropy random: remove unneeded hash of a portion of the entropy pool random: always update the entropy pool under the spinlock
