Pull crypto updates from Herbert Xu: "Here is the crypto update for 5.3: API: - Test shash interface directly in testmgr - cra_driver_name is now mandatory Algorithms: - Replace arc4 crypto_cipher with library helper - Implement 5 way interleave for ECB, CBC and CTR on arm64 - Add xxhash - Add continuous self-test on noise source to drbg - Update jitter RNG Drivers: - Add support for SHA204A random number generator - Add support for 7211 in iproc-rng200 - Fix fuzz test failures in inside-secure - Fix fuzz test failures in talitos - Fix fuzz test failures in qat" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (143 commits) crypto: stm32/hash - remove interruptible condition for dma crypto: stm32/hash - Fix hmac issue more than 256 bytes crypto: stm32/crc32 - rename driver file crypto: amcc - remove memset after dma_alloc_coherent crypto: ccp - Switch to SPDX license identifiers crypto: ccp - Validate the the error value used to index error messages crypto: doc - Fix formatting of new crypto engine content crypto: doc - Add parameter documentation crypto: arm64/aes-ce - implement 5 way interleave for ECB, CBC and CTR crypto: arm64/aes-ce - add 5 way interleave routines crypto: talitos - drop icv_ool crypto: talitos - fix hash on SEC1. crypto: talitos - move struct talitos_edesc into talitos.h lib/scatterlist: Fix mapping iterator when sg->offset is greater than PAGE_SIZE crypto/NX: Set receive window credits to max number of CRBs in RxFIFO crypto: asymmetric_keys - select CRYPTO_HASH where needed crypto: serpent - mark __serpent_setkey_sbox noinline crypto: testmgr - dynamically allocate crypto_shash crypto: testmgr - dynamically allocate testvec_config crypto: talitos - eliminate unneeded 'done' functions at build time ...
