Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu: "API: - Enforce the setting of keys for keyed aead/hash/skcipher algorithms. - Add multibuf speed tests in tcrypt. Algorithms: - Improve performance of sha3-generic. - Add native sha512 support on arm64. - Add v8.2 Crypto Extentions version of sha3/sm3 on arm64. - Avoid hmac nesting by requiring underlying algorithm to be unkeyed. - Add cryptd_max_cpu_qlen module parameter to cryptd. Drivers: - Add support for EIP97 engine in inside-secure. - Add inline IPsec support to chelsio. - Add RevB core support to crypto4xx. - Fix AEAD ICV check in crypto4xx. - Add stm32 crypto driver. - Add support for BCM63xx platforms in bcm2835 and remove bcm63xx. - Add Derived Key Protocol (DKP) support in caam. - Add Samsung Exynos True RNG driver. - Add support for Exynos5250+ SoCs in exynos PRNG driver" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (166 commits) crypto: picoxcell - Fix error handling in spacc_probe() crypto: arm64/sha512 - fix/improve new v8.2 Crypto Extensions code crypto: arm64/sm3 - new v8.2 Crypto Extensions implementation crypto: arm64/sha3 - new v8.2 Crypto Extensions implementation crypto: testmgr - add new testcases for sha3 crypto: sha3-generic - export init/update/final routines crypto: sha3-generic - simplify code crypto: sha3-generic - rewrite KECCAK transform to help the compiler optimize crypto: sha3-generic - fixes for alignment and big endian operation crypto: aesni - handle zero length dst buffer crypto: artpec6 - remove select on non-existing CRYPTO_SHA384 hwrng: bcm2835 - Remove redundant dev_err call in bcm2835_rng_probe() crypto: stm32 - remove redundant dev_err call in stm32_cryp_probe() crypto: axis - remove unnecessary platform_get_resource() error check crypto: testmgr - test misuse of result in ahash crypto: inside-secure - make function safexcel_try_push_requests static crypto: aes-generic - fix aes-generic regression on powerpc crypto: chelsio - Fix indentation warning crypto: arm64/sha1-ce - get rid of literal pool crypto: arm64/sha2-ce - move the round constant table to .rodata section ...
