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 Cc: Jim Kukunas <james.t.kukunas@linux.intel.com> Cc: H.
