Why do you need ARCH_THUNDER? If it's just to change this default, please don't bother - we don't do this kind of thing on x86, so why should it be done here? Just ensure that NR_CPUS is appropriately adjusted. Alternatively, look at how x86 deals with this (with X86_BIGSMP / MAXSMP). -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net.
