Since this control knob is effective only for x86_64, should we enable this
only for this architecture?
This should be under a CONFIG option that depends on the architecture
selected. I don't see a reason why it will not be useful for other archs.
Using a CONFIG option looks fine to me. I just want to make sure that
arches that don't support it won't have a useless control knob show up.
