The start/stop_critical_timings are called from arch/x86/kernel/process.c
in the cpu_idle loop function.

Remove the ones in the cpuidle driver.

For this one I need an ACK from Len.

Len, any objections?

Rafael,

this patch is not dependent from any patch in the series, is it possible
you apply the patchset except this patch ?

May be you can apply it later when Len acks it, or I can resend it, no ?

I have a lot of code consolidation patches awaiting for this patchset to
be merged.

Thanks

OK, I'll take the rest of your patches in this series (except for [1/9]
which also is not depended on by anything AFAICS).
