Why not the other way around? Just define IRQ_PER_CPU to 0 on architectures not needing it and add a FAT comment there, that this disables it. Or make it a config option. Then just leave the code as is and let GCC optimize the dead code away without any changes in the C file. It works, I just checked it ;-) Regards Ingo Oeser
