The reason this was not done so far was lack of genuine IPI_IRQ for ARC700, as we don't have a SMP version of core yet (which might change soon thx to EZChip). Nevertheles to increase the build coverage, we need to allow CONFIG_SMP for ARC700 and still be able to run it on a UP platform (nsim or AXS101) with a UP Device Tree (SMP-on-UP) The build itself requires some define for IPI_IRQ and even a dummy value is fine since that code won't run anyways.
