The right way to do this is to move the definitions which should only
be used by arch/arm/mach-at91/irq.c to that file or a header file along
side that file, and find a place in include/linux for the remainder.
I notice arch/arm/mach-at91/pm.c makes use of some of the register
definitions:
at91_irq_suspend();
pr_debug("AT91: PM - wake mask %08x, pm state %d\n",
/* remember all the always-wake irqs */
(at91_pmc_read(AT91_PMC_PCSR)
| (1 << AT91_ID_FIQ)
| (1 << AT91_ID_SYS)
| (at91_extern_irq))
& at91_aic_read(AT91_AIC_IMR),
state);
at91_irq_suspend() is in arch/arm/mach-at91/irq.c already, so there's no
reason that fragment can't be moved there.
That leaves: at91_aic_handle_irq, at91_aic5_handle_irq, NR_AIC_IRQS and
NR_AIC5_IRQS, which if you did patch 3 first, would leave you with just
the NR_.*_IRQS definitions to find a home for.
