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 4.10:
API:
- add skcipher walk interface
- add asynchronous compression (acomp) interface
- fix algif_aed AIO handling of zero buffer
Algorithms:
- fix unaligned access in poly1305
- fix DRBG output to large buffers
Drivers:
- add support for iMX6UL to caam
- fix givenc descriptors (used by IPsec) in caam
- accelerated SHA256/SHA512 for ARM64 from OpenSSL
- add SSE CRCT10DIF and CRC32 to ARM/ARM64
- add AEAD support to Chelsio chcr
- add Armada 8K support to omap-rng"
