           * linux/dev/arch/i386/kernel/irq.c (linux_intr): Disable interrupts
           if the driver requested it through request_irq().

           * linux/dev/drivers/block/ide.c (read_intr): Set the IRQ handler before
           issuing a request.
           (write_intr): Likewise.
           (multwrite_intr): Likewise.
