[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Martin K. Petersen <martin.petersen@xxxxxxxxxx>

commit 94e5395d2403c8bc2504a7cbe4c4caaacb7b8b84 upstream.

First generation MPT Fusion controllers can not translate WRITE SAME
when the attached device is a SATA drive. Disable WRITE SAME support.
