random: revert
random: backport updates from Linux master (3.13-rc4) lib, net: make isodigit() public and use it Andy Shevchenko random: add debugging code to detect early use of get_random_bytes() Theodore Ts'o random: initialize the last_time field in struct timer_rand_state Theodore Ts'o random: don't zap entropy count in rand_initialize() Theodore Ts'o random: printk notifications for urandom pool initialization Theodore Ts'o random: make add_timer_randomness() fill the nonblocking pool first Theodore Ts'o random: convert DEBUG_ENT to tracepoints Theodore Ts'o random: push extra entropy to the output pools Theodore Ts'o random: drop trickle mode Theodore Ts'o random: adjust the generator polynomials in the mixing function slightly Theodore Ts'o random: speed up the fast_mix function by a factor of four Theodore Ts'o random: cap the rate which the /dev/urandom pool gets reseeded Theodore Ts'o random: optimize the entropy_store structure Theodore Ts'o random: optimize spinlock use in add_device_randomness() Theodore Ts'o random: fix the tracepoint for get_random_bytes(_arch) Theodore Ts'o random: account for entropy loss due to overwrites H. Peter Anvin random: allow fractional bits to be tracked H. Peter Anvin random: statically compute poolbitshift, poolbytes, poolbits H. Peter Anvin random: mix in architectural randomness earlier in extract_buf() Theodore Ts'o random: allow architectures to optionally define random_get_entropy() Theodore Ts'o random: run random_int_secret_init() run after all late_initcalls Theodore Ts'o char: Convert use of typedef ctl_table to struct ctl_table Joe Perches 1 random: fix accounting race condition with lockless irq entropy_count update Jiri Kosina drivers/char/random.c: fix priming of last_data Jarod Wilson lib/string_helpers: introduce generic string_unescape Andy Shevchenko random: fix locking dependency with the tasklist_lock Theodore Ts'o locking: Various static lock initializer fixes Thomas Gleixner random: prime last_data value per fips requirements Jarod Wilson random: fix debug format strings Jiri Kosina random: make it possible to enable debugging without rebuild Jiri Kosina random: mix in architectural randomness in extract_buf() H. Peter Anvin random: Add comment to random_initialize() Tony Luck random: add tracepoints for easier debugging and verification Theodore Ts'o
