Pull crypto updates from Herbert Xu:
 "Here is the crypto update for 4.12:

  API:
   - Add batch registration for acomp/scomp
   - Change acomp testing to non-unique compressed result
   - Extend algorithm name limit to 128 bytes
   - Require setkey before accept(2) in algif_aead

  Algorithms:
   - Add support for deflate rfc1950 (zlib)

  Drivers:
   - Add accelerated crct10dif for powerpc
   - Add crc32 in stm32
   - Add sha384/sha512 in ccp
   - Add 3des/gcm(aes) for v5 devices in ccp
   - Add Queue Interface (QI) backend support in caam
   - Add new Exynos RNG driver
   - Add ThunderX ZIP driver
   - Add driver for hardware random generator on MT7623 SoC"
