The section mismatch warning on x86 is not shown by default because there are still so many problems.

This is actually different - it is generated by the compiler. I am not sure why we only get them on PowerPC. Rusty suggested that we could dynamically create a file that just referenced all the EXPORTed symbols (we know what they are) and try to link that. Then we would find all the static ones. PowerPC would still find them earlier, of course, but since a lot of poeple only compile for x86(_64), they may not get as far as the PowerPC builds. The other section mismatch warnings (generated by an external program) are certainly suppressed by default on all architectures. I enable them for some of my builds, and it is not too bad at the moment (apart from a couple of particular subsystems - and Sparc :-)). I suspect that if we reenabled them by default, they would be fixed fairly quickly.

I think it has to do with how function descriptors work on powerpc. Code references to static (local) things work different from how global scope references work. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
