Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto update from Herbert Xu: "Here is the crypto update for 4.2: API: - Convert RNG interface to new style. - New AEAD interface with one SG list for AD and plain/cipher text. All external AEAD users have been converted. - New asymmetric key interface (akcipher). Algorithms: - Chacha20, Poly1305 and RFC7539 support. - New RSA implementation. - Jitter RNG. - DRBG is now seeded with both /dev/random and Jitter RNG. If kernel pool isn't ready then DRBG will be reseeded when it is. - DRBG is now the default crypto API RNG, replacing krng. - 842 compression (previously part of powerpc nx driver). Drivers: - Accelerated SHA-512 for arm64. - New Marvell CESA driver that supports DMA and more algorithms. - Updated powerpc nx 842 support. - Added support for SEC1 hardware to talitos" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (292 commits) crypto: marvell/cesa - remove COMPILE_TEST dependency crypto: algif_aead - Temporarily disable all AEAD algorithms crypto: af_alg - Forbid the use internal algorithms crypto: echainiv - Only hold RNG during initialisation crypto: seqiv - Add compatibility support without RNG crypto: eseqiv - Offer normal cipher functionality without RNG crypto: chainiv - Offer normal cipher functionality without RNG crypto: user - Add CRYPTO_MSG_DELRNG crypto: user - Move cryptouser.h to uapi crypto: rng - Do not free default RNG when it becomes unused crypto: skcipher - Allow givencrypt to be NULL crypto: sahara - propagate the error on clk_disable_unprepare() failure crypto: rsa - fix invalid select for AKCIPHER crypto: picoxcell - Update to the current clk API crypto: nx - Check for bogus firmware properties crypto: marvell/cesa - add DT bindings documentation crypto: marvell/cesa - add support for Kirkwood and Dove SoCs crypto: marvell/cesa - add support for Orion SoCs crypto: marvell/cesa - add allhwsupport module parameter crypto: marvell/cesa - add support for all armada SoCs ...
