Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6

Pull crypto updates from Herbert Xu:
 "API:
   - Enforce the setting of keys for keyed aead/hash/skcipher
     algorithms.
   - Add multibuf speed tests in tcrypt.

  Algorithms:
   - Improve performance of sha3-generic.
   - Add native sha512 support on arm64.
   - Add v8.2 Crypto Extentions version of sha3/sm3 on arm64.
   - Avoid hmac nesting by requiring underlying algorithm to be unkeyed.
   - Add cryptd_max_cpu_qlen module parameter to cryptd.

  Drivers:
   - Add support for EIP97 engine in inside-secure.
   - Add inline IPsec support to chelsio.
   - Add RevB core support to crypto4xx.
   - Fix AEAD ICV check in crypto4xx.
   - Add stm32 crypto driver.
   - Add support for BCM63xx platforms in bcm2835 and remove bcm63xx.
   - Add Derived Key Protocol (DKP) support in caam.
   - Add Samsung Exynos True RNG driver.
   - Add support for Exynos5250+ SoCs in exynos PRNG driver"
