This still misses out on Ben's objection that its impossible to get this
right at compile time for many kernels, since they can boot and run on
many different subarchs.

Completely agree.  The Kconfig-time stuff should probably just be a knob
to turn it off completely, if anything.

ok. Here is my thought. So to address Ben's concern, it would be better
to have this as a variable with a default value (and the platform can
override ride it). And a mm/Kconfig to disable it?
Kindly let me know whether this will work.

Thanks for review comments.
