9 * 11/24/98 S.Eranian updated TIMER_IRQ and irq_canonicalize
10 * 01/20/99 S.Eranian added keyboard interrupt
11 * 02/29/00 D.Mosberger moved most things into hw_irq.h
15 #define NR_IRQ_VECTORS NR_IRQS
18 * IRQ line status macro IRQ_PER_CPU is used
20 #define ARCH_HAS_IRQ_PER_CPU
23 irq_canonicalize (int irq
)
26 * We do the legacy thing here of pretending that irqs < 16
27 * are 8259 irqs. This really shouldn't be necessary at all,
28 * but we keep it here as serial.c still uses it...
