   - Free default RNG on module exit

  Algorithms:
   - Fix vli multiplication carry overflow in ecc

   - Disallow RSA PKCS#1 SHA-1 sig algs in FIPS mode
   - Filter out async aead implementations at alloc in krb5
   - Fix non-parallel fallback by rstoring callback in pcrypt
   - Validate poly1305 template argument in chacha20poly1305

  Drivers:
   - Add sysfs PCI reset support to qat
