Could you please explain why fsys call? Sys_getcpu takes about 600cycles on 1.6GHz Montecito. Do we need to save these cycles?
Andi Kleen used to lecture me every so often why it is important to have fast vgetcpu on x86-64 (I don't think ia64 is excluded from that). His lecture is also all over the lkml mailing list. - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
