Subject: [GIT PULL] MD update for 4.9

Hi Linus,
Please pull MD update for 4.9. 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

Thanks,
Shaohua
