[PATCH] arch/i386/kernel/irq.c: do_IRQ()

[William Jhun]

Though a comment in arch/i386/kernel/irq.c: do_IRQ() clearly states:

         * 0 return value means that this irq is already being
         * handled by some other CPU. (or is disabled)

it seems that the function can only ever return (1). We wrote some low-level
interrupt handling code that depends on the correct value of this function.
Is the following patch what was initially desired? (patched against 2.4.18
tarball from kernel.org...)

Thanks,
William Jhun
