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 4.9:
API:
- The crypto engine code now supports hashes.
Algorithms:
- Allow keys >= 2048 bits in FIPS mode for RSA.
Drivers:
- Memory overwrite fix for vmx ghash.
- Add support for building ARM sha1-neon in Thumb2 mode.
- Reenable ARM ghash-ce code by adding import/export.
- Reenable img-hash by adding import/export.
- Add support for multiple cores in omap-aes.
- Add little-endian support for sha1-powerpc.
- Add Cavium HWRNG driver for ThunderX SoC"
