If CONFIG_X86_MCE_AMD=n, mce_hygon_feature_init will call the other

the kernel will run without MCE support.
So my question was rather ironic but I guess irony can't travel through
mail. So let me paraphrase: is that a use case you wanna support?
Because I'd advise very strongly against !MCE kernels.
In most of the normal use cases MCE is necessary. Rarely in some cases
such as for test purpose MCE may be unselected.
