Add missing #inclusions of <linux/irq.h> to a whole bunch of files that should really include it. Note that this can replace #inclusions of <asm/irq.h>. This is required for the patch to sort out irqflags handling function naming to compile on MIPS. The problem is that these files require access to things like setup_irq() - which isn't available by #including <linux/interrupt.h> Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Ralf Baechle <ralf@linux-mips.org>
