Merge tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random
Pull randomness updates from Ted Ts'o: - initialize the random driver earler - fix CRNG initialization when we trust the CPU's RNG on NUMA systems - other miscellaneous cleanups and fixes. * tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random: random: add a spinlock_t to struct batched_entropy random: document get_random_int() family random: fix CRNG initialization when random.trust_cpu=1 random: move rand_initialize() earlier random: only read from /dev/random after its pool has received 128 bits drivers/char/random.c: make primary_crng static drivers/char/random.c: remove unused stuct poolinfo::poolbits drivers/char/random.c: constify poolinfo_table
