Author: hselasky Date: Mon Feb 19 12:25:32 2018 New Revision: 329568 URL: https://svnweb.freebsd.org/changeset/base/329568 Log: MFC r326765: ofed: Define barriers for mips and arm. I used the strongest barriers available on the architectures, so if the future analysis show that it is excessive, the barriers could be relaxed. Still, it is unlikely that it is meaningful to run IB on 32bit ARM or current MIPS machines, so the change is to make WITH_OFED to pass tinderbox.
