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
