[GIT PULL] random number generator fixes for 5.18-rc5

[Jason A. Donenfeld]

Hi Linus,

Please pull the following two sets of fixes for 5.18-rc5:

- Eric noticed that the memmove() in crng_fast_key_erasure() was bogus, so
  this has been changed to a memcpy() and the confusing situation clarified
  with a detailed comment.

- [Half]SipHash documentation updates from Bagas and Eric, after Eric pointed
  out that the use of HalfSipHash in random.c made a bit of the text
  potentially misleading.

That's it since the push I sent you in rc3 -- really very small -- so
hopefully things are done for 5.18.

Thanks,
Jason
