It seems recent changes (SVN r335873?) may have broken drm-next-kmod ..

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:

i've just built a kernel with this patch applied, rebooted into it and was able to build the drm-next-kmod port.  i am also running X without issues so far with this configuration.

cheers,
