No reason, its just an old patch and I didn't know we should be avoiding
setup_irq().
I have just removed ompic_ipi_irqaction and replaced setup_irq() with this:
ret = request_irq(irq, ompic_ipi_handler, IRQF_PERCPU,
"ompic_ipi", NULL);
if (ret)
goto out_irq_disp;
I did some testing and it looks to be working fine.

Thank You,
I will send another V once I get a bit more feedback on the other parts of the
series.
