Hmm, it probably needs a EXPORT_SYMBOL. The previous change only fixed the in kernel build. Does it work with this patch? -Andi Export _proxy_pda for gcc 4.2 The symbol is not actually used, but the compiler unforunately generates a (unused) reference to it. This can happen even in modules. So export it.
