Yep. Firmware features are also on the list. I figured I'd do CPU features first though since they are the ones that started bugging me. > The same stuff is obviously possible for cur_cpu_spec->cpu_features as well. > Do you think that it will help there? Nice. It won't be quite as easy to do compile-time for cpu features. pSeries will need all cpus enabled since we have them all on various machines, etc. I guess Powermac/Maple could benefit from it. In the end it depends on how hairy the implementation would get vs performance improvement. -Olof - 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/
