Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto update from Herbert Xu: - CTR(AES) optimisation on x86_64 using "by8" AVX. - arm64 support to ccp - Intel QAT crypto driver - Qualcomm crypto engine driver - x86-64 assembly optimisation for 3DES - CTR(3DES) speed test - move FIPS panic from module.c so that it only triggers on crypto modules - SP800-90A Deterministic Random Bit Generator (drbg). - more test vectors for ghash. - tweak self tests to catch partial block bugs. - misc fixes. * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (94 commits) crypto: drbg - fix failure of generating multiple of 2**16 bytes crypto: ccp - Do not sign extend input data to CCP crypto: testmgr - add missing spaces to drbg error strings crypto: atmel-tdes - Switch to managed version of kzalloc crypto: atmel-sha - Switch to managed version of kzalloc crypto: testmgr - use chunks smaller than algo block size in chunk tests crypto: qat - Fixed SKU1 dev issue crypto: qat - Use hweight for bit counting crypto: qat - Updated print outputs crypto: qat - change ae_num to ae_id crypto: qat - change slice->regions to slice->region crypto: qat - use min_t macro crypto: qat - remove unnecessary parentheses crypto: qat - remove unneeded header crypto: qat - checkpatch blank lines crypto: qat - remove unnecessary return codes crypto: Resolve shadow warnings crypto: ccp - Remove "select OF" from Kconfig crypto: caam - fix DECO RSR polling crypto: qce - Let 'DEV_QCE' depend on both HAS_DMA and HAS_IOMEM ...
