[GIT PULL] random number generator fixes for 7.3-rc6

["Jason A. Donenfeld" <Jason@zx2c4.com>]

Hi Linus,

Please pull the following small set of updates to the random number generator
and related code:

- VMGENID memory needs to be mapped with the decrypted tag, so that SEV-SNP
  machines can boot.
- A fix for an initialization race in VMGENID, followed by a cleanup.
- Trivial kernel doc cleanups in siphash and random.c. Arguably this isn't a
  true bug fix and would be for 7.4, but it's so insignificant, that I figure
  it's fine.
- A fix for a new compilation failure with recent clang on PPC and RISC-V, due
  to generating an out-of-line memset in the vDSO.

The last fix has a conflict with linux-next, which you might encounter in the
7.4 merge window: https://lore.kernel.org/all/ar5-4Yq3wtmXTWnD@sirena.org.uk/T/#u

Thanks,
Jason
