Merge branch 'for-4.7-zac' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

Pull libata ZAC support from Tejun Heo:
 "This contains Zone ATA Command support for Shingled Magnetic Recording
  devices.

  In addition to sending the new commands down to the device, as ZAC
  commands depend on getting a lot of responses from the device, piping
  up responses is beefed up too.  However, it doesn't involve changes to
  libata core mechanism or its interaction with upper layers, so I'm not
  expecting too many fallouts.

  Kudos to Hannes for driving SMR support"
