Subject: [PATCH 0/3][RFC] tracing/rcu: Add _rcuidle() tracepoint to handle rcu_idle_exit() tracepoints

This is an RFC patch set for what I plan on pushing out to handle
the tracepoints that are called from within rcu_idle_exit() sections.

The first patch is the tracepoint infrastructure,
the second is the changes in x86
the third is the changes in the cpuidle driver.

I see there's use cases in the arm arch, but as that is in flux, I'll
let the arm folks deal with those.

Steven Rostedt (3):
      tracing/rcu: Add trace_##name##__rcuidle() static tracepoint for inside rcu_idle_exit() sections
      x86/tracing: Denote the power and cpuidle tracepoints as _rcuidle()
      cpuidle/tracing: Denote the tracepoints as being in rcu_idle_exit() section
