Thanks! I found that the above change was not enough since CRIS had
some extra (incorrect) prototypes for setup_irq that caused compile
errors, so I've added the the following patch to the cris-tree:
From: Christoph Hellwig <hch@lst.de>
Subject: [PATCH] CRIS: convert to asm-generic/hardirq.h
Convert CRIS to use asm-generic/hardirq.h
Also remove unneeded (incorrect) prototypes for setup_irq().
