If anyone has any objections, please let me know. ------------------ From: Eric Biggers commit ac53977611428db3bc0b4ac0225e19c3e08ae50b upstream. Since the AVX2 optimized ARIA code uses YMM registers, execute vzeroupper before returning from it. This is needed to avoid degrading the performance of any later SSE code that may happen to be executed.
