Linus Torvalds 52f6c588c7 Add wait_for_random_bytes() and get_random_*_wait() functions so that
callers can more safely get random bytes if they can block until the
 CRNG is initialized.
 
 Also print a warning if get_random_*() is called before the CRNG is
 initialized.  By default, only one single-line warning will be printed
 per boot.  If CONFIG_WARN_ALL_UNSEEDED_RANDOM is defined, then a
 warning will be printed for each function which tries to get random
 bytes before the CRNG is initialized.  This can get spammy for certain
 architecture types, so it is not enabled by default.
