I think it would be better to turn the logic around here,
otherwise you get into trouble when

I think it would be better to turn the logic around here,
otherwise you get into trouble when enabling multiple
platforms, out of which some have IPI
ARC common code to enable a SMP system + ISS provided SMP extensions.
ARC700 natively lacks SMP support, hence some of the core features are
are only enabled if SoCs have the necessary h/w pixie-dust. This
includes:
-Inter Processor Interrupts (IPI)
-Cache coherency
-load-locked/store-conditional
