These DM changes were layered ontop of linux-block.git to avoid
conflicts associated with all the 4.13 block changes.

The following changes since commit 443bd90f2cca9dec3db9ef9460a9c2a6f095f789:

  nvme: host: unquiesce queue in nvme_kill_queues() (2017-06-18 20:52:58 -0600)

  dm zoned: fix overflow when converting zone ID to sectors (2017-07-05 16:08:47 -0400)

Please pull, thanks!
Mike

----------------------------------------------------------------
- Add the ability to select or poll /dev/mapper/control to wait for
  events from multiple DM devices.

- Convert DM's printk macros over to using pr_<level> macros.

- Add a big-endian variant of plain64 IV to dm-crypt.

- Add support for zoned (aka SMR) devices to DM core.  DM kcopyd was
  also improved to provide a sequential write feature needed by zoned
  devices.

- Introduce DM zoned target that provides support for host-managed zoned
  devices, the result dm-zoned device acts as a drive-managed interface
  to the underlying host-managed device.

- A DM raid fix to avoid using BUG() for error handling.
