Hi all,
These here patches are the result of Mathieu and Steve trying to get commit
865e63b04e9b2 ("tracing: Add back in rcu_irq_enter/exit_irqson() for rcuidle
tracepoints") reverted again.
One of the things discovered is that tracing MUST NOT happen before nmi_enter()
or after nmi_exit(). I've only fixed x86, but quickly gone through other
architectures and there is definitely more stuff to be fixed (simply grep for
nmi_enter in your arch).
