2.3.2 alpha disable_irq patch

In 2.3.2 there is:

+disable_irq(unsigned int irq_nr)
+{
+ /* This works non-SMP, and SMP until we write code to distribute
+ interrupts to more that cpu 0. */
+ disable_irq_nosync(irq_nr);

If I understand well this mean that on Alpha all irqs goes to the same
CPU0 in SMP. But disable_irq() can run also on CPU1 so I think the code
above is wrong.

Does somebody tried my Alpha patch I posted to the kernel list some days
ago?
