Note that this will insta-kill all trace_*_rcuidle() tracepoint that are actually used in rcuidle.
A git-grep seems to suggest the remaining users are:
- arch/arm - arch/arm64 -- IPI tracepoint that are ordered incorrectly in their entry code,
- runtime pm - common clk -- these both need re-ordering somehow
- trace_preemptirq -- this is going to be interesting for those archs that idle with IRQs enabled
- printk -- we shouldn't be printk()-ing from idle, and if we are, missing this is the least of our problems.
