(Well, the -march anyways) I'd say benefits of compiling p4-optimized code are questionable. Are you sure your kernel will run faster, not slower? Benchmark numbers? Or it's only warm and fuzzy feeling? Warm and fuzzy feelings of kernels compiled for very new processors quickly disappear when you try to boot e.g. 486 with them ;) -- vda - 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/
