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 4.15: API: - Disambiguate EBUSY when queueing crypto request by adding ENOSPC. This change touches code outside the crypto API. - Reset settings when empty string is written to rng_current. Algorithms: - Add OSCCA SM3 secure hash. Drivers: - Remove old mv_cesa driver (replaced by marvell/cesa). - Enable rfc3686/ecb/cfb/ofb AES in crypto4xx. - Add ccm/gcm AES in crypto4xx. - Add support for BCM7278 in iproc-rng200. - Add hash support on Exynos in s5p-sss. - Fix fallback-induced error in vmx. - Fix output IV in atmel-aes. - Fix empty GCM hash in mediatek. Others: - Fix DoS potential in lib/mpi. - Fix potential out-of-order issues with padata" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (162 commits) lib/mpi: call cond_resched() from mpi_powm() loop crypto: stm32/hash - Fix return issue on update crypto: dh - Remove pointless checks for NULL 'p' and 'g' crypto: qat - Clean up error handling in qat_dh_set_secret() crypto: dh - Don't permit 'key' or 'g' size longer than 'p' crypto: dh - Don't permit 'p' to be 0 crypto: dh - Fix double free of ctx->p hwrng: iproc-rng200 - Add support for BCM7278 dt-bindings: rng: Document BCM7278 RNG200 compatible crypto: chcr - Replace _manual_ swap with swap macro crypto: marvell - Add a NULL entry at the end of mv_cesa_plat_id_table[] hwrng: virtio - Virtio RNG devices need to be re-registered after suspend/resume crypto: atmel - remove empty functions crypto: ecdh - remove empty exit() MAINTAINERS: update maintainer for qat crypto: caam - remove unused param of ctx_map_to_sec4_sg() crypto: caam - remove unneeded edesc zeroization crypto: atmel-aes - Reset the controller before each use crypto: atmel-aes - properly set IV after {en,de}crypt hwrng: core - Reset user selected rng by writing "" to rng_current ...
