It's 7 years now that we merged irq timings into the kernel, but we
still have zero users for this.
I'm tempted to declare this experiment failed and remove the whole thing
for good.
Comments?
I worked on an irq cpuidle governor which had better results than the
menu governor and equal than the teo governor. But I never succeed to
have better results without putting some arbitrary when computing the
next event.
At one moment, Daniel Bristot de Oliveira (Cc'ed) was thinking to may be
use it for the deadline scheduler.
Ulf (Cc'ed) may be has a plan for the next event for the CPU cluster.
But if no one has plan to use it, there is no good reason to keep it and
I'm fine if we remove it.
