Merge tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random
Pull random changes from Ted Ts'o:
"Change /dev/random so that it uses the CRNG and only blocking if the
CRNG hasn't initialized, instead of the old blocking pool. Also clean
up archrandom.h, and some other miscellaneous cleanups"
