Sure.

When I started this work, there were 18k+ W=1 warnings in the kernel.
Now there are more like 3k. I don't think anyone is to blame per say,
it's just something that people haven't particularly cared about up
until this point.

One of my main aims is to clean-up W=1s to the point where enabling
them would become normal practice, rather than the situation we're in
presently where enabling them just dominates the build-log, making
them more trouble than they're worth.

I'd rather they didn't say.

This would void the main aim of this effort.

It's the first time this has been requested, but it's your train-set
and I will do whatever you ask.
