Pull crypto library updates from Eric Biggers:
 "This is the main crypto library pull request for 6.19. It includes:

   - Add SHA-3 support to lib/crypto/, including support for both the
     hash functions and the extendable-output functions. Reimplement the
     existing SHA-3 crypto_shash support on top of the library.

     This is motivated mainly by the upcoming support for the ML-DSA
     signature algorithm, which needs the SHAKE128 and SHAKE256
     functions. But even on its own it's a useful cleanup.

     This also fixes the longstanding issue where the
     architecture-optimized SHA-3 code was disabled by default.

   - Add BLAKE2b support to lib/crypto/, and reimplement the existing
     BLAKE2b crypto_shash support on top of the library.

     This is motivated mainly by btrfs, which supports BLAKE2b
     checksums. With this change, all btrfs checksum algorithms now have
     library APIs. btrfs is planned to start just using the library
     directly.

     This refactor also improves consistency between the BLAKE2b code
     and BLAKE2s code. And as usual, it also fixes the issue where the
     architecture-optimized BLAKE2b code was disabled by default.

   - Add POLYVAL support to lib/crypto/, replacing the existing POLYVAL
     support in crypto_shash. Reimplement HCTR2 on top of the library.

     This simplifies the code and improves HCTR2 performance. As usual,
     it also makes the architecture-optimized code be enabled by
     default. The generic implementation of POLYVAL is greatly improved
     as well.

   - Clean up the BLAKE2s code

   - Add FIPS self-tests for SHA-1, SHA-2, and SHA-3"
