ah. EISA got too copies

/* ISA interrupts are always polarity zero edge triggered,
* when listed as conforming in the MP table. */

#define default_ISA_trigger(idx) (0)
#define default_ISA_polarity(idx) (0)

/* EISA interrupts are always polarity zero and can be edge or level
* trigger depending on the ELCR value. If an interrupt is listed as
* EISA conforming in the MP table, that means its trigger type must
* be read in from the ELCR */

#define default_EISA_trigger(idx) (EISA_ELCR(mp_irqs[idx].mp_srcbusirq))
#define default_EISA_polarity(idx) default_ISA_polarity(idx)

/* PCI interrupts are always polarity one level triggered,
* when listed as conforming in the MP table. */

#define default_PCI_trigger(idx) (1)
#define default_PCI_polarity(idx) (1)

/* EISA interrupts are always polarity zero and can be edge or level
* trigger depending on the ELCR value. If an interrupt is listed as
* EISA conforming in the MP table, that means its trigger type must

#define default_EISA_trigger(idx) (EISA_ELCR(mp_irqs[idx].mp_srcbusirq))
#define default_EISA_polarity(idx) default_ISA_polarity(idx)


need to remove the extra one.
