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
