As you write in commit a934a57a42f6 ("scripts/misc-check: check missing
#include <linux/export.h> when W=1") this adds now 4000+ extra warnings
for W=1 builds, which makes such builds more or less useless for me.

Also the commit only describes what you want to achieve, but not why.
I can only guess that you want to reduce header dependencies(?).

Don't get me wrong, I can address all of this trivial churn for s390, however
enforcing so many extra warnings to everyone with W=1 builds doesn't look like
the right approach to me.
