- * This table basically keeps track of level vs edge triggered interrupts.
- * Windows has 250+ entries, but it seems stupid to replicate that since the PIC
- * can't actually have that many.
- *
- * When a level interrupt is registered, the respective pointer in this table is
- * modified to point to a dimiss routine for level interrupts instead.
- *
- * The other thing this table does is special case IRQ7, IRQ13 and IRQ15:
- *
- * - If an IRQ line is deasserted before it is acknowledged due to a noise spike
- * generated by an expansion device (since the IRQ line is low during the 1st
- * acknowledge bus cycle), the i8259 will keep the line low for at least 100ns
- * When the spike passes, a pull-up resistor will return the IRQ line to high.
- * Since the PIC requires the input be high until the first acknowledge, the
- * i8259 knows that this was a spurious interrupt, and on the second interrupt
- * acknowledge cycle, it reports this to the CPU. Since no valid interrupt has
- * actually happened Intel hardcoded the chip to report IRQ7 on the master PIC
- * and IRQ15 on the slave PIC (IR7 either way).
- *
- * "ISA System Architecture", 3rd Edition, states that these cases should be
- * handled by reading the respective Interrupt Service Request (ISR) bits from
- * the affected PIC, and validate whether or not IR7 is set. If it isn't, then
- * the interrupt is spurious and should be ignored.
- *
- * Note that for a spurious IRQ15, we DO have to send an EOI to the master for
- * IRQ2 since the line was asserted by the slave when it received the spurious
- * IRQ15!
- *
- * - When the 80287/80387 math co-processor generates an FPU/NPX trap, this is
- * connected to IRQ13, so we have to clear the busy latch on the NPX port.
