Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu: "Here is the crypto update for 4.10: API: - add skcipher walk interface - add asynchronous compression (acomp) interface - fix algif_aed AIO handling of zero buffer Algorithms: - fix unaligned access in poly1305 - fix DRBG output to large buffers Drivers: - add support for iMX6UL to caam - fix givenc descriptors (used by IPsec) in caam - accelerated SHA256/SHA512 for ARM64 from OpenSSL - add SSE CRCT10DIF and CRC32 to ARM/ARM64 - add AEAD support to Chelsio chcr - add Armada 8K support to omap-rng" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (148 commits) crypto: testmgr - fix overlap in chunked tests again crypto: arm/crc32 - accelerated support based on x86 SSE implementation crypto: arm64/crc32 - accelerated support based on x86 SSE implementation crypto: arm/crct10dif - port x86 SSE implementation to ARM crypto: arm64/crct10dif - port x86 SSE implementation to arm64 crypto: testmgr - add/enhance test cases for CRC-T10DIF crypto: testmgr - avoid overlap in chunked tests crypto: chcr - checking for IS_ERR() instead of NULL crypto: caam - check caam_emi_slow instead of re-lookup platform crypto: algif_aead - fix AIO handling of zero buffer crypto: aes-ce - Make aes_simd_algs static crypto: algif_skcipher - set error code when kcalloc fails crypto: caam - make aamalg_desc a proper module crypto: caam - pass key buffers with typesafe pointers crypto: arm64/aes-ce-ccm - Fix AEAD decryption length MAINTAINERS: add crypto headers to crypto entry crypt: doc - remove misleading mention of async API crypto: doc - fix header file name crypto: api - fix comment typo crypto: skcipher - Add separate walker for AEAD decryption ..
