Pull x86 tracing updates from Ingo Molnar:
 "This tree adds IRQ vector tracepoints that are named after the handler
  and which output the vector #, based on a zero-overhead approach that
  relies on changing the IDT entries, by Seiji Aguchi.

  The new tracepoints look like this:

   # perf list | grep -i irq_vector
    irq_vectors:local_timer_entry                      [Tracepoint event]
    irq_vectors:local_timer_exit                       [Tracepoint event]
    irq_vectors:reschedule_entry                       [Tracepoint event]
    irq_vectors:reschedule_exit                        [Tracepoint event]
    irq_vectors:spurious_apic_entry                    [Tracepoint event]
    irq_vectors:spurious_apic_exit                     [Tracepoint event]
    irq_vectors:error_apic_entry                       [Tracepoint event]
    irq_vectors:error_apic_exit                        [Tracepoint event]
   [...]"
