ARM and ARM64 are the only two architectures implementing arch_cpu_idle_prepare() simply to call local_fiq_enable().
We have secondary_start_kernel() already calling local_fiq_enable() and this is done a second time in arch_cpu_idle_prepare() in that case. And enabling FIQs has nothing to do with idling the CPU to start with.
So let's introduce init_fiq_boot_cpu() to take care of FIQs on the boot CPU and remove arch_cpu_idle_prepare(). This is now done a bit earlier at late_initcall time but this shouldn't make a difference in practice i.e. when FIQs are actually used.

What kind of review did you do when giving that attributation?
I did the review to the best of my knowledge and with good will.
I read your comment on this patch and I learnt one more thing.
Today, I am smarter than yesterday and dumber than tomorrow :)
