Why can't you use the C3STOP feature so that the arch-timer isn't used when
you go idle?

That would mean falling back to broadcast timer, right? That's not
necessarily on the local CPU so wakeups would often wake two CPUs.

You can prevent that if the hardware supports it with the
CLOCK_EVT_DYNIRQ flag on the broadcast timer.

CLOCK_EVT_FEAT_DYNIRQ seems to be the flag. Cool, thanks.
