The only subtle difference is that alpha uses ACTUAL_NR_IRQS and

Change the generic implementation to deal with ACTUAL_NR_IRQS if
defined.
The IRQF_DISABLED printing is pointless, as we nowadays run all

handle_prio_irq is almost identical with handle_fasteoi_irq. The
subtle differences are
1) The handler checks for IRQ_DISABLED after the device handler has
been called. In case it's set it masks the interrupt.
2) When the handler sees IRQ_DISABLED on entry it masks the interupt
in the same way as handle_fastoei_irq, but does not set the
IRQ_PENDING flag.
3) Instead of gracefully handling a recursive interrupt it crashes the
kernel.
#1 is just relevant when a device handler calls disable_irq_nosync()
and it does not matter whether we mask the interrupt right away or
not. We handle lazy masking for disable_irq anyway, so there is no
real reason to have this extra mask in place.
#2 will prevent the resend of a pending interrupt, which can result in
lost interrupts for edge type interrupts. For level type interrupts
the resend is a noop in the generic code. According to the
datasheet all interrupts are level type, so marking them as such
will result in the exact same behaviour as the private
handle_prio_irq implementation.
#3 is just stupid. Crashing the kernel instead of handling a problem
gracefully is just wrong. With the current semantics- all handlers
run with interrupts disabled - this is even more wrong.
Rename ack to eoi, remove the unused mask_ack, switch to
handle_fasteoi_irq and remove the private function.
