Hm, what was wrong with config_enabled(CONFIG_SMP)?
The IS_BUILTIN() macro is 1) shouting loud, needlessly 2)
somewhat confusing for the CONFIG_SMP case: of course SMP is
'built in', not modular - and the fact that 'built in' also
implies 'enabled' is lost in that naming variant.
So I think IS_BUILTIN() makes more sense for genuine tri-state
config knobs, and bools like CONFIG_SMP should se
config_enabled()..
Thanks,
Ingo
