Well, it is this part:
"But on a plain simple laptop or workstation which has CPU hotplug,
would it make sense for the crash ranges to get updated too when CPUs
are offlined?
If so, I think you want this code present there too, without a Kconfig
item."
IOW, if this thing doesn't make sense to have on the majority of
machines out there - and memory hotplug machines are not the majority -
then it should be behind a Kconfig item which is default off and gets
enabled only when the user selects crash and memory hotplug...
I'd say.
