   - the AEAD interface transition is now complete.
   - add top-level skcipher interface.

  Drivers:

   - x86-64 acceleration for chacha20/poly1305.
   - add sunxi-ss Allwinner Security System crypto accelerator.
   - add RSA algorithm to qat driver.
   - add SRIOV support to qat driver.
   - add LS1021A support to caam.
   - add i.MX6 support to caam"
