This looks generally like a good idea to me.

However, I think that we should do something similar for the coccinelle
scripts. Indeed, why carrying a private copy of them?

Doing this only for checkpatch.pl would be an incomplete step.

So we'd also need an option for coccinelle, similar to the --checkpatch
that you introduce.

And my thinking that may be it would be better to introduce a --upstream
option which would specify the upstream branch name, or tag, or commit
ID, or another refspec. Aiaiai would pick checkpatch.pl and coccinelle
scripts from there.

Or it could be a path to the upstream tree. And Aiaiai would pick
checkpatch.pl and coccinelle scripts from there.

I am not sure which is better. The latter is certainly easier to
implement.

I can try to implement one of these, which one do you prefer? I find
both useful, but would vote for the second one.

Thanks!
