That looks like an unholy marriage between the preprocessor, a function definition, and a Duff Device. :) Do it like this: #ifdef CONFIG_X86_32 asmlinkage sys_iopl( prototype_needed) { /* the whole thing */ } #else asmlinkage long sys_iopl(alternate_prototype) { /* the entire body */ } #endif You'll still need some ad-croc ifdef-ery at the call site to make it use the correct prototype (unless you can come up with some clever way of making the two use the same prototype, possibly by passing a dummy argument on some architectures...
