Having these selected doesn't change how the kernel is compiled or how the kernel uses the code which these provide. These mainly control which files are built. They also control indirectly how the code is called - but the ultimate decision is made by the CPU which is detected and the block in __fa526_proc_info. So, having these symbols enabled (provided the right ones for FA526 are also enabled) makes no difference. So I don't buy your explanation. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
