Subject: [GIT PULL] libata ZAC changes for v4.7-rc1

Hello, Linus.

This pull request 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.

Thanks.
