Explain that to me.
There should *be* no resume.
ACPI doesn't suspend/resume on its own, I hope.
It is all done by the top-level suspend/resume code, not by ACPI. ACPI is

All of CONFIG_HOTPLUG_CPU.
Len, this is not about ACPI code. This is about CONFIG_HOTPLUG_CPU. Which
I don't want. And which you forced on me.
