There's no prompt for this and no way to override what you've done here
without hacking Kconfig/.config files.

It's also completely wrong to say "CONFIG_ARCH_MEMORY_PROBE is supported
on powerpc only." It works just fine on x86. In fact, I was just using
it today without ACPI being around.

I'd really prefer you don't do this. Do you really have random
processes on your system poking at random sysfs files and then
complaining when things break?
