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"
