Well, actually the ldr (I assume you mean this one):
ldrne \irqnr, [\base, #INTCPS_SIR_IRQ_OFFSET]
was being done everytime, since presumably, at least one of the
"pending" bits would be set otherwise how would we get to this
interrupt? Which bring up a point - why bother even checking the
pending bits at all? Just grab the irqnr, check for spurious and
exit.
