If CONFIG_SMP=n:

drivers/irqchip/irq-gic.c: In function '__gic_init_bases':
drivers/irqchip/irq-gic.c:1165:4: error: implicit declaration of
function 'set_smp_cross_call' [-Werror=implicit-function-declaration]
    set_smp_cross_call(gic_raise_softirq);
    ^

There's no dummy for the CONFIG_SMP=n case, so you either have to
keep the #ifdef, or add a dummy.
