Subject: [PATCH v4 20/24] crypto: x86/ciphers - load based on CPU features
Like commit aa031b8f702e ("crypto: x86/sha512 - load based on CPU
features"), add module aliases based on CPU feature bits for
modules not implementing hash algorithms:
aegis, aesni, aria
blake2s, blowfish
camellia, cast5, cast6, chacha, curve25519
des3_ede
serpent, sm4
twofish
Signed-off-by: Robert Elliott <elliott@....com>
---
v4 Remove CPU feature checks that are unreachable because
x86_match_cpu already handles them. Make curve25519 match
on ADX and check BMI2.
