Subject: [PATCHv2 0/3] tracing: function graph output for wakeup tracer

hi,

adding function graph output to irqsoff tracer.
The graph output is enabled by setting new 'display-graph'
trace option.

The v2 updates are based on comments by Frederic Weisbecker
and Steven Rostedt, also rebased to latest master.


v2:
- librarized common functions from irqs/preemptoff tracers
- using local_save_flags instead disabling irqs to get the flags
  in wakeup_graph_return/wakeup_graph_entry


attached patches:
- 1/3 proper check for irq_depth routines
- 2/3 librarize graph related irqs/preempts off calls
- 3/3 graph support for wakeup tracer


plz let me know what you think

wbr,
jirka
