At the moment I'm just trying to squash sparse warnings on powerpc. This
particular catch came from making something static via a dodgy python
script and then Andrew finding it was EXPORTed. Removing the EXPORT
threw the warning - so it's a bit more complex than just a sparse
warning.

I think powerpc has the missing prototype warnings enabled and -Werror
as well.

Andrew Donellan was telling me there's a Coccinelle script that looks
for things that are both static and EXPORTed - maybe that's worth
following up on this point?

Regards,
Daniel
