Subject: [PATCH v2 0/6] Add AVX512 optimized gen_syndrome, xor_syndrome and recovery functions

This is the version 2 patch series for adding AVX512 optimized gen_syndrome,
xor_syndrome and recovery functions.

Optimization of RAID6 using AVX512 instructions should improve the
RAID6 performance.These patches are tested and observed the improvement
in performance.

Changes since v1:
1) Added xor_syndrome functions to avx512 optimized raid6.

Gayatri Kammela (6):
  lib/raid6: Add AVX512 optimized gen_syndrome functions
  lib/raid6: Add AVX512 optimized recovery functions
  lib/raid6/test/Makefile: Add avx512 gen_syndrome and recovery
    functions
  lib/raid6: Add AVX512 optimized xor_syndrome functions
  (DO NOT APPLY) lib/raid6: Add unroll by 8 to AVX512 optimized
    gen_syndrome functions
  (DO NOT APPLY) lib/raid6: Add unroll by 8 to AVX512 optimized
