Seems like Kconfig allow config option duplication, but it use default state from first.
If we add "config NUMA\n def_bool n" somewhere in generic Kconfig, default will be n if
Kconfig see this declaration first.

Correct.
And as n is default there is no need to specify it.
But please add a help text that explain the symbol - even if it is not
visible in menuconfig.

So does that mean that a simple

config NUMA
	bool
	help
		some help text

in mm/Kconfig will have no effect on the defaults and dependencies if
"config NUMA" is specified elsewhere?  (except to add the needed
__enabled_CONFIG_NUMA defines, of course).  If that is the case, then
that is what we should add, right?
