If we want to be even more explicit about this, then if the CPU level selected by the user is greater than Pentium-M (or whatever is was the oldest CPU that didn't have NX support --- Arjan?) we shouldn't offer this choice at all, and force CONFIG_HIGHMEM64G. We can give the user a choice if CONFIG_EMBEDDED is enabled, but otherwise, if the CPU level is new enough, I think we can safely make the argument that for nearly all systems, they have enough memory and speed that perhaps we should just simply always use HIGHMEM64G. - Ted - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
