Currently the x86_64 trace code from entry.S calls a

The problem is that the trace records the call coming from
trace_hardirqs_on_thunk and not the location in entry.S, which makes it
difficult to find exactly where a latency lies.

When tracing both hard irqs off, as well as preemption off, we get
ridiculous latency times caused by cpu_idle.
What is happening is that the cpu_idle code in i386 and x86_64 has
either interrupts off or preemption off. Since it calls __schedule
instead of schedule, it can do this.
