This added information is much nicer, thank you!
But I cannot make cpu_in_idle() as __init because it is invoked at runtime by nmi_cpu_backtrace().
Also, I do not see any .LVL79. Might this be a compiler temporary?
And I cannot see how this patch could have affected cpu_in_idle().
Might this instead be a false positive caused by the fact that cpu_in_idle() references __cpuidle_text_start and __cpuidle_text_end, both of which are defined in vmlinux.lds.h?
Thanx, Paul
