    crypto: x86/aria - implement aria-avx512 · c970d420
    Taehee Yoo authored
    aria-avx512 implementation uses AVX512 and GFNI.
    It supports 64way parallel processing.
    So, byteslicing code is changed to support 64way parallel.
    And it exports some aria-avx2 functions such as encrypt() and decrypt().
    
    AVX and AVX2 have 16 registers.
    They should use memory to store/load state because of lack of registers.
    But AVX512 supports 32 registers.
    So, it doesn't require store/load in the s-box layer.
    It means that it can reduce overhead of store/load in the s-box layer.
    Also code become much simpler.
