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 ..

+// Cortex-A53	2.38		15.5 (+115%)	10.0 (+150%(***))

+// X-Gene			20.0 (+100%)	12.8 (+300%(***))
+// Mongoose	2.36		13.0 (+50%)	8.36 (+33%)
+//
+// (*)	Software SHA256 results are of lesser relevance, presented
+//	mostly for informational purposes.
+// (**)	The result is a trade-off: it's possible to improve it by
+//	10% (or by 1 cycle per round), but at the cost of 20% loss
+//	on Cortex-A53 (or by 4 cycles per round).
+// (***)	Super-impressive coefficients over gcc-generated code are
+//	indication of some compiler "pathology", most notably code
+//	generated with -mgeneral-regs-only is significanty faster
+//	and the gap is only 40-90%.
+//
+// October 2016.
+//
+// Originally it was reckoned that it makes no sense to implement NEON
+// version of SHA256 for 64-bit processors. This is because performance
+// improvement on most wide-spread Cortex-A5x processors was observed
+// to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+// observed that 32-bit NEON SHA256 performs significantly better than
+// 64-bit scalar version on *some* of the more recent processors. As
+// result 64-bit NEON version of SHA256 was added to provide best
+// all-round performance. For example it executes ~30% faster on X-Gene
+// and Mongoose. [For reference, NEON version of SHA512 is bound to
+// deliver much less improvement, likely *negative* on Cortex-A5x.
+// Which is why NEON support is limited to SHA256.]

+# SHA256/512 for ARMv8.
+#
+# Performance in cycles per processed byte and improvement coefficient
+# over code generated with "default" compiler:
+#
+#		SHA256-hw	SHA256(*)	SHA512
+# Apple A7	1.97		10.5 (+33%)	6.73 (-1%(**))
+# Cortex-A53	2.38		15.5 (+115%)	10.0 (+150%(***))
+# Cortex-A57	2.31		11.6 (+86%)	7.51 (+260%(***))
+# Denver	2.01		10.5 (+26%)	6.70 (+8%)
+# X-Gene			20.0 (+100%)	12.8 (+300%(***))
+# Mongoose	2.36		13.0 (+50%)	8.36 (+33%)
+#
+# (*)	Software SHA256 results are of lesser relevance, presented
+#	mostly for informational purposes.
+# (**)	The result is a trade-off: it's possible to improve it by
+#	10% (or by 1 cycle per round), but at the cost of 20% loss
+#	on Cortex-A53 (or by 4 cycles per round).
+# (***)	Super-impressive coefficients over gcc-generated code are
+#	indication of some compiler "pathology", most notably code
+#	generated with -mgeneral-regs-only is significanty faster
+#	and the gap is only 40-90%.
+#
+# October 2016.
+#
+# Originally it was reckoned that it makes no sense to implement NEON
+# version of SHA256 for 64-bit processors. This is because performance
+# improvement on most wide-spread Cortex-A5x processors was observed
+# to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+# observed that 32-bit NEON SHA256 performs significantly better than
+# 64-bit scalar version on *some* of the more recent processors. As
+# result 64-bit NEON version of SHA256 was added to provide best
+# all-round performance. For example it executes ~30% faster on X-Gene
+# and Mongoose. [For reference, NEON version of SHA512 is bound to
+# deliver much less improvement, likely *negative* on Cortex-A5x.
+# Which is why NEON support is limited to SHA256.]

+// improvement on most wide-spread Cortex-A5x processors was observed
+// to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+// observed that 32-bit NEON SHA256 performs significantly better than
+// 64-bit scalar version on *some* of the more recent processors. As
+// result 64-bit NEON version of SHA256 was added to provide best
+// all-round performance. For example it executes ~30% faster on X-Gene
+// and Mongoose. [For reference, NEON version of SHA512 is bound to
+// deliver much less improvement, likely *negative* on Cortex-A5x.
+// Which is why NEON support is limited to SHA256.]
