Merge tag 'v6.7-p1' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu: "API: - Add virtual-address based lskcipher interface - Optimise ahash/shash performance in light of costly indirect calls - Remove ahash alignmask attribute Algorithms: - Improve AES/XTS performance of 6-way unrolling for ppc - Remove some uses of obsolete algorithms (md4, md5, sha1) - Add FIPS 202 SHA-3 support in pkcs1pad - Add fast path for single-page messages in adiantum - Remove zlib-deflate Drivers: - Add support for S4 in meson RNG driver - Add STM32MP13x support in stm32 - Add hwrng interface support in qcom-rng - Add support for deflate algorithm in hisilicon/zip" * tag 'v6.7-p1' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (283 commits) crypto: adiantum - flush destination page before unmapping crypto: testmgr - move pkcs1pad(rsa,sha3-*) to correct place Documentation/module-signing.txt: bring up to date module: enable automatic module signing with FIPS 202 SHA-3 crypto: asymmetric_keys - allow FIPS 202 SHA-3 signatures crypto: rsa-pkcs1pad - Add FIPS 202 SHA-3 support crypto: FIPS 202 SHA-3 register in hash info for IMA x509: Add OIDs for FIPS 202 SHA-3 hash and signatures crypto: ahash - optimize performance when wrapping shash crypto: ahash - check for shash type instead of not ahash type crypto: hash - move "ahash wrapping shash" functions to ahash.c crypto: talitos - stop using crypto_ahash::init crypto: chelsio - stop using crypto_ahash::init crypto: ahash - improve file comment crypto: ahash - remove struct ahash_request_priv crypto: ahash - remove crypto_ahash_alignmask crypto: gcm - stop using alignmask of ahash crypto: chacha20poly1305 - stop using alignmask of ahash crypto: ccm - stop using alignmask of ahash net: ipv6: stop checking crypto_ahash_alignmask ...
