tracing, genirq: add irq enter and exit trace events Impact: add new tracepoints Add them to the generic IRQ code, that way every architecture gets these new tracepoints, not just x86. Using Steve's new 'TRACE_FORMAT', I can get function graph trace as follows using the original two IRQ tracepoints: 3) \| handle_IRQ_event() { 3) \| /* (irq_handler_entry) irq=28 handler=eth0 / 3) \| e1000_intr_msi() { 3) 2.460 us \| __napi_schedule(); 3) 9.416 us \| } 3) \| / (irq_handler_exit) irq=28 handler=eth0 return=handled */ 3) + 22.935 us \| } Signed-off-by: Jason Baron <jbaron@redhat.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Acked-by: Peter Zijlstra <peterz@infradead.org> Acked-by: Masami Hiramatsu <mhiramat@redhat.com> Cc: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Cc: Mathieu Desnoyers <compudj@krystal.dyndns.org> Cc: "Frank Ch.
