Browse Source 
Pull crypto updates from Herbert Xu:
 "API:
   - Add linear akcipher/sig API
   - Add tfm cloning (hmac, cmac)
   - Add statesize to crypto_ahash

  Algorithms:
   - Allow only odd e and restrict value in FIPS mode for RSA
   - Replace LFSR with SHA3-256 in jitter
   - Add interface for gathering of raw entropy in jitter

  Drivers:
   - Fix race on data_avail and actual data in hwrng/virtio
   - Add hash and HMAC support in starfive
   - Add RSA algo support in starfive
   - Add support for PCI device 0x156E in ccp"
