If anyone has any objections, please let me know. ------------------ From: Eric Biggers commit 60892a384aa1e65d0e703e1c513417bdf0c80777 upstream. Since the AVX-512 optimized ARIA code uses ZMM 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.
