[PATCH] m68k: cleanup amiga irq numbering
Fix amiga irq numbering, so they are after the generic IRQ_AUTO defines and remove the IRQ_AMIGA_AUTO defines. Signed-off-by: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
