The speculation tracker insn in my recent patch set for CVE-2017-5753 was missing a mode on the UNSPEC. Although this didn't break the build, it did cause an unnecessary warning from the MD parsing mechanism that I missed at the time. It's a trivial fix, as follows: * config/aarch64/aarch64.md (speculation_tracker): Set the mode for the UNSPEC. Committed to trunk.
