Thanks for pointing out the script/results.

It's also worth stressing, I think, the fact that some of those are from
the MAINTAINERS file; I stumbled accross one of them yesterday:

http://lkml.kernel.org/r/1525707655-3542-1-git-send-email-andrea.parri@amarulasolutions.com

False positives apart (e.g., the four references in tools/memory-model/),
those are regressions from my POV: please do not (consiously) merge more!
