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.
