Merge tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux

Pull crypto library updates from Eric Biggers:

- Add support for verifying ML-DSA signatures.

ML-DSA (Module-Lattice-Based Digital Signature Algorithm) is a
recently-standardized post-quantum (quantum-resistant) signature
algorithm. It was known as Dilithium pre-standardization.

The first use case in the kernel will be module signing. But there
are also other users of RSA and ECDSA signatures in the kernel that
might want to upgrade to ML-DSA eventually.

- Improve the AES library:

- Make the AES key expansion and single block encryption and
decryption functions use the architecture-optimized AES code.
Enable these optimizations by default.

- Support preparing an AES key for encryption-only, using about
half as much memory as a bidirectional key.

- Replace the existing two generic implementations of AES with a
single one.

- Simplify how Adiantum message hashing is implemented. Remove the
"nhpoly1305" crypto_shash in favor of direct lib/crypto/ support for
NH hashing, and enable optimizations by default.

lib/crypto: nh: Add NH library

Add support for the NH "almost-universal hash function" to lib/crypto/,
specifically the variant of NH used in Adiantum.

This will replace the need for the "nhpoly1305" crypto_shash algorithm.
All the implementations of "nhpoly1305" use architecture-optimized code
only for the NH stage; they just use the generic C Poly1305 code for the
Poly1305 stage. We can achieve the same result in a simpler way using
an (architecture-optimized) nh() function combined with code in
crypto/adiantum.c that passes the results to the Poly1305 library.

This commit begins this cleanup by adding the nh() function. The code
is derived from crypto/nhpoly1305.c and include/crypto/nhpoly1305.h.
