Pull block fixes from Jens Axboe:
 "A small collection of fixes that should go into this series. This
  contains:

   - NVMe pull request from Christoph, with various fixes for nvme
     proper and nvme-fc.

   - disable runtime PM for blk-mq for now.

     With scsi now defaulting to using blk-mq, this reared its head as
     an issue. Longer term we'll fix up runtime PM for blk-mq, for now
     just disable it to prevent a hang on laptop resume for some folks.

   - blk-mq CPU <-> hw queue map fix from Christoph.

   - xen/blkfront pull request from Konrad, with two small fixes for the
     blkfront driver.

   - a few fixups for nbd from Joseph.

   - a stable fix for pblk from Javier"
