More likely, people will just re-implement them incorrectly. However, the rdtsc() definition in the kernel is weird (and removable, I think there are no more users -- I have it removed in my MSR driver rewrite tree which I need to get off my arse and push.) Most users would expect the rdtscll() functionality with the rdtsc() name. -hpa - 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/
