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
