What about other asm header dependencies? cpu_logical_map is needed for

That's one of the down-sides to moving this code out of arch/arm - your
existing set of five patches adds to the required asm headers (eg, it
now needs set_smp_cross_call() from ARMs asm/smp.h, whereas it didn't
need that before) and any SMP architecture re-using the GIC will need
to provide this function whether or not they use the SPI facility.
