Pull crypto library updates from Eric Biggers:
 "This is the main crypto library pull request for 6.17. The main focus
  this cycle is on reorganizing the SHA-1 and SHA-2 code, providing
  high-quality library APIs for SHA-1 and SHA-2 including HMAC support,
  and establishing conventions for lib/crypto/ going forward:

   - Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares
     most of the SHA-512 code) into lib/crypto/. This includes both the
     generic and architecture-optimized code. Greatly simplify how the
     architecture-optimized code is integrated. Add an easy-to-use
     library API for each SHA variant, including HMAC support. Finally,
     reimplement the crypto_shash support on top of the library API.

   - Apply the same reorganization to the SHA-256 code (and also SHA-224
     which shares most of the SHA-256 code). This is a somewhat smaller
     change, due to my earlier work on SHA-256. But this brings in all
     the same additional improvements that I made for SHA-1 and SHA-512.

  There are also some smaller changes:

   - Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code
     from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For
     these algorithms it's just a move, not a full reorganization yet.

   - Fix the MIPS chacha-core.S to build with the clang assembler.

   - Fix the Poly1305 functions to work in all contexts.

   - Fix a performance regression in the x86_64 Poly1305 code.

   - Clean up the x86_64 SHA-NI optimized SHA-1 assembly code.

  Note that since the new organization of the SHA code is much simpler,
  the diffstat of this pull request is negative, despite the addition of
  new fully-documented library APIs for multiple SHA and HMAC-SHA
  variants.

  These APIs will allow further simplifications across the kernel as
  users start using them instead of the old-school crypto API. (I've
  already written a lot of such conversion patches, removing over 1000
  more lines of code. But most of those will target 6.18 or later)"
