    Pull MD updates from Shaohua Li:
     "This update includes:
       - new AVX512 instruction based raid6 gen/recovery algorithm
       - a couple of md-cluster related bug fixes
       - fix a potential deadlock
       - set nonrotational bit for raid array with SSD
       - set correct max_hw_sectors for raid5/6, which hopefuly can improve
         performance a little bit
       - other minor fixes"
