Thanks.

I did clean-up all of the GPU warnings already a couple of years ago,
but they seem to have crept back over time.  It would be great if we
could put some extra checks in place to prevent them in the future.

My aim, albeit ambitious, is to clean-up all of the W=1 warnings in the
kernel, then have them promoted to W=0, so they warn more loudly during
development, thus keeping them from reappearing.
