    lib/raid6: Add AVX512 optimized recovery functions · 13c520b2
    Gayatri Kammela authored Aug 13, 2016
    Optimize RAID6 recovery functions to take advantage of
    the 512-bit ZMM integer instructions introduced in AVX512.
    
    AVX512 optimized recovery functions, which is simply based
    on recov_avx2.c written by Jim Kukunas
    
    This patch was tested and benchmarked before submission on
    a hardware that has AVX512 flags to support such instructions
