Wrong vector, my bad. However 2) still stands in my opinion. We don't have "ipi raise" trace point for x86. RESCHEDULE_VECTOR, CALL_FUNCTION_SINGLE_VECTOR, as well as TLB invalidation vectors are essentially inter-processor-interrupts if I'm not mistaken. Would a patch adding such trace point be considered here? Thanks, Wojtek
