I've applied this series to https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git/log/?h=libcrypto-next, excluding the following 2 patches which are waiting on benchmark results from the s390 folks: lib/crypto: sha3: Support arch overrides of one-shot digest functions lib/crypto: s390/sha3: Add optimized one-shot SHA-3 digest functions I'd be glad to apply those too if they're shown to be worthwhile. Note: I also reordered the commits in libcrypto-next to put the new KUnit test suites (blake2b and sha3) last, and to put the AES-GCM improvements on a separate branch that's merged in. This will allow making separate pull requests for the tests and the AES-GCM improvements, which I think aligns with what Linus had requested before (https://lore.kernel.org/linux-crypto/CAHk-=wi5d4K+sF2L=tuRW6AopVxO1DDXzstMQaECmU2QHN13KA@mail.gmail.com/). - Eric
