The old NO_IRQ define some platforms had was long ago declared obsolete and wrong. FRV should therefore not be re-introducing this, especially as IRQs are usually unsigned in the kernel. The "no IRQ" case is defined to be zero and Linus made this rather clear at the time. arch/frv shows no dependancy on this but it might show up driver fixes needing doing I guess Signed-off-by: Alan Cox <alan@redhat.com> Acked-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
