As I've said already in this thread, it is all about what "ACPI-based
CPU hotplug" means to each of us.

I know what it means to me: Running the code that is compiled when
ACPI_HOTPLUG_CPU is set via the processor scan handler.

I'm not entirely sure what it means to you.

You are saying that the config option name needs to be changed,
because it is going to stay N for ARM64 and it will support
"ACPI-based CPU hotplug" and I'm not sure what exactly you mean by
this.

To me, this just means that ARM64 is not going to use the processor
scan handler in the way it is used on x86.

Sorry, but I'm just not convinced by your justification.

And I don't have to suffer this kind of abuse.  Sorry.
