I do know that.


But your suggestion was:

static inline unsigned int get_nmi_count(int cpu)
{
return cpu_x86_64 ? cpu_pda(cpu)->__nmi_count : nmi_count(cpu);
}

And Jeremy said "It would be nice if CONFIG_* expanded to 0/1".


My point was simply that like most of the fun^Wproblems we already have
in kconfig also here the tristate logic we need would make stuff more
tricky.
