For some architectures, yes. As John Stultz pointed out, on many of the older embedded platforms (which are many of the ones with out a get_cycles function), the only clocksource they have is the jiffies time source anyway. So I'd much rather take each architecture one at a time, and fix them right. - 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/
