Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto update from Herbert Xu: "API: - Add helper for simple skcipher modes. - Add helper to register multiple templates. - Set CRYPTO_TFM_NEED_KEY when setkey fails. - Require neither or both of export/import in shash. - AEAD decryption test vectors are now generated from encryption ones. - New option CONFIG_CRYPTO_MANAGER_EXTRA_TESTS that includes random fuzzing. Algorithms: - Conversions to skcipher and helper for many templates. - Add more test vectors for nhpoly1305 and adiantum. Drivers: - Add crypto4xx prng support. - Add xcbc/cmac/ecb support in caam. - Add AES support for Exynos5433 in s5p. - Remove sha384/sha512 from artpec7 as hardware cannot do partial hash" [ There is a merge of the Freescale SoC tree in order to pull in changes required by patches to the caam/qi2 driver. ] * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (174 commits) crypto: s5p - add AES support for Exynos5433 dt-bindings: crypto: document Exynos5433 SlimSSS crypto: crypto4xx - add missing of_node_put after of_device_is_available crypto: cavium/zip - fix collision with generic cra_driver_name crypto: af_alg - use struct_size() in sock_kfree_s() crypto: caam - remove redundant likely/unlikely annotation crypto: s5p - update iv after AES-CBC op end crypto: x86/poly1305 - Clear key material from stack in SSE2 variant crypto: caam - generate hash keys in-place crypto: caam - fix DMA mapping xcbc key twice crypto: caam - fix hash context DMA unmap size hwrng: bcm2835 - fix probe as platform device crypto: s5p-sss - Use AES_BLOCK_SIZE define instead of number crypto: stm32 - drop pointless static qualifier in stm32_hash_remove() crypto: chelsio - Fixed Traffic Stall crypto: marvell - Remove set but not used variable 'ivsize' crypto: ccp - Update driver messages to remove some confusion crypto: adiantum - add 1536 and 4096-byte test vectors crypto: nhpoly1305 - add a test vector with len % 16 != 0 crypto: arm/aes-ce - update IV after partial final CTR block ...
