221e00d1fc crypto: x86 - Add missing RETs 
Add explicit RETs to the tail calls of AEGIS and MORUS crypto algorithms
otherwise they run into INT3 padding due to

  ("x86/asm: Pad assembly functions with INT3 instructions")

leading to spurious debug exceptions.

Mike Galbraith <efault@gmx.de> took care of all the remaining callsites.

6ecc9d9ff9 crypto: x86 - Add optimized MORUS implementations 
This patch adds optimized implementations of MORUS-640 and MORUS-1280,
utilizing the SSE2 and AVX2 x86 extensions.

For MORUS-1280 (which operates on 256-bit blocks) we provide both AVX2
and SSE2 implementation. Although SSE2 MORUS-1280 is slower than AVX2
MORUS-1280, it is comparable in speed to the SSE2 MORUS-640.
