Merge tag 'random-5.19-rc2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator fixes from Jason Donenfeld:
 - A fix for a 5.19 regression for a case in which early device tree
   initializes the RNG, which flips a static branch.
   On most plaforms, jump labels aren't initialized until much later, so
   this caused splats. On a few mailing list threads, we cooked up easy
   fixes for arm64, arm32, and risc-v. But then things looked slightly
   more involved for xtensa, powerpc, arc, and mips. And at that point,
   when we're patching 7 architectures in a place before the console is
   even available, it seems like the cost/risk just wasn't worth it.
   So random.c works around it now by checking the already exported
   `static_key_initialized` boolean, as though somebody already ran into
   this issue in the past. I'm not super jazzed about that; it'd be
   prettier to not have to complicate downstream code. But I suppose
   it's practical.
 - A few small code nits and adding a missing __init annotation.
 - A change to the default config values to use the cpu and bootloader's
   seeds for initializing the RNG earlier.
   This brings them into line with what all the distros do (Fedora/RHEL,
   Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at
   least), and moreover will now give us test coverage in various test
   beds that might have caught the above device tree bug earlier.
 - A change to WireGuard CI's configuration to increase test coverage
   around the RNG.
 - A documentation comment fix to unrelated maintainerless CRC code that
   I was asked to take, I guess because it has to do with polynomials
   (which the RNG thankfully no longer uses).
* tag 'random-5.19-rc2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random:
  wireguard: selftests: use maximum cpu features and allow rng seeding
  random: remove rng_has_arch_random()
  random: credit cpu and bootloader seeds by default
  random: do not use jump labels before they are initialized
  random: account for arch randomness in bits
  random: mark bootloader randomness code as __init
  random: avoid checking crng_ready() twice in random_init()
  crc-itu-t: fix typo in CRC ITU-T polynomial comment
