Merge tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random
Pull random updates from Ted Ts'o:
"Some changes to trust cpu-based hwrng (such as RDRAND) for
initializing hashed pointers and (optionally, controlled by a config
option) to initialize the CRNG to avoid boot hangs"
* tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random:
random: Make crng state queryable
random: remove preempt disabled region
random: add a config option to trust the CPU's hwrng
vsprintf: Add command line option debug_boot_weak_hash
vsprintf: Use hw RNG for ptr_key
random: Return nbytes filled from hw RNG
random: Fix whitespace pre random-bytes work
