Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu:
"Algorithms:
- Drop alignment requirement for data in aesni
- Use synchronous seeding from the /dev/random in DRBG
- Reseed nopr DRBGs every 5 minutes from /dev/random
- Add KDF algorithms currently used by security/DH
- Fix lack of entropy on some AMD CPUs with jitter RNG
Drivers:
- Add support for the D1 variant in sun8i-ce
- Add SEV_INIT_EX support in ccp
- PFVF support for GEN4 host driver in qat
- Compression support for GEN4 devices in qat
- Add cn10k random number generator support"
