Wouldn't that be
+ if (hwif->port_ops && hwif->port_ops->test_irq(hwif) &&
+ hwif->port_ops->clear_irq(hwif) == 0)
(this was never compiled?)

I think you mean:
case MAC_IDE_BABOON:
base = BABOON_BASE;
- ack_intr = NULL;
+ macide_port_ops.clear_irq = NULL;
Why is this broken into two patches? Bisecting in between doesn't work.
