Merge tag 'v6.1-p1' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6

Pull crypto updates from Herbert Xu:
 "API:
   - Feed untrusted RNGs into /dev/random
   - Allow HWRNG sleeping to be more interruptible
   - Create lib/utils module
   - Setting private keys no longer required for akcipher
   - Remove tcrypt mode=1000
   - Reorganised Kconfig entries

  Algorithms:
   - Load x86/sha512 based on CPU features
   - Add AES-NI/AVX/x86_64/GFNI assembler implementation of aria cipher

  Drivers:
   - Add HACE crypto driver aspeed"
