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"
