Consequently, the contents of asm/arch/irq.h (which mostly contain a definition for fixup_irq()) have not been used. Hence, remove asm/arch/irq.h. Some machine support files incorrectly included this file, making little or no use of the contents. Move the contents to a local include file, and remove those include statements as well.
