I'd be willing to be that this will work just fine. But, I think we can do it without any static state at all, if we just pass a runtime-or-not flag down into the arch_add_memory() call chain. I'll code that up so we can compare to yours. -- Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
