[Jens Axboe]

Hi Linus,

On top of the 4.3 core block IO changes, here are the driver related
changes for 4.3. Basically just NVMe and nbd this time around. This pull
request contains:

- NVMe:

        - PRACT PI improvement from Alok Pandey.
        - Cleanups and improvements on submission queue doorbell and
          writing, using CMB if available. From Jon Derrick.
        - From Keith, support for setting queue maximum segments, and
          reset support.
        - Also from Jon, fixup of u64 division issue on 32-bit archs and
          wiring up of the reset support through and ioctl.
        - Two small cleanups from Matias and Sunad

- Various code cleanups and fixes from Markus Pargmann.

Please pull!
