  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.
