So X86_MPPARSE is not needed when SMP is not enabled? here's the condition: config X86_MPPARSE def_bool y depends on (X86_32 && (X86_LOCAL_APIC && !X86_VISWS)) || X86_64 64-bit has it unconditionally, 32-bit has it on SMP, UP-IOAPIC or UP-local-APIC mode. [ (and VISWS is an ugly complication we should try to eradicate similarly to NUMAQ, if possible :-) ] Ingo
