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
a pure helper, and if you've changed that, then I think we need to revert
more than a few lines.

And it's the *top*level* code that selects HOTPLUG_CPU. Through
SUSPEND_SMP (which will select HOTPLUG_CPU) and SOFTWARE_SUSPEND.

This is why it's so *totally* and *utterly* bogus for ACPI to select
features that it has nothign what-so-ever to do with.

In other words: ACPI isn't in the driving seat.
