It seems recent changes (SVN r335873?) may have broken

It breaks also graphics/drm-stable-kmod (see PR 229484,
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229484, same
error as you described
above) and also emulators/virtualbox-ose-kmod. As long as CURRENT
revision is < r335873,
those kmod compile well.
We are looking into why both the drm ports fail.

I haven't yet tested an amd64 kernel with this, but I think this
change to sys/amd64/include/atomic.h
might fix it:
