So, all you need is:
include/linux/init.h
include/asm-arm/mach/time.h
include/asm-arm/mach/arch.h
And maybe one or two more.

Should it be ...[NR_IRQS] ?

You are doing "eb01_irq_prtable[irq] >> 5" always.

Use consistent style for "for" statements and brackets. Like in the next line.

Please, remove trailing whitespace from this patch. There is quite a few of
it.
