-+/* A lot of complication here is taken away because:
-+ *
-+ * 1) We handle one interrupt and return, sitting in a loop and moving across
-+ * all the pending IRQ bits in the cause register is _NOT_ the answer, the

-+ *
-+ * 2) We need not check against bits in the status register IRQ mask, that
-+ * would make this routine slow as hell.
-+ *
-+ * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in
-+ * between like BSD spl() brain-damage.
-+ *
-+ * Furthermore, the IRQs on the MIPS board look basically (barring software
-+ * IRQs which we don't use at all and all external interrupt sources are
-+ * combined together on hardware interrupt 0 (MIPS IRQ 2)) like:
-+ *
-+ * MIPS IRQ Source
-+ * -------- ------
-+ * 0 Software (ignored)
-+ * 1 Software (ignored)
-+ * 2 Combined hardware interrupt (hw0)
-+ * 3 Hardware (ignored)
-+ * 4 Hardware (ignored)
-+ * 5 Hardware (ignored)
-+ * 6 Hardware (ignored)
-+ * 7 R4k timer (what we use)
-+ *
-+ * Note: On the SEAD board thing are a little bit different.
-+ * Here IRQ 2 (hw0) is wired to the UART0 and IRQ 3 (hw1) is wired
-+ * wired to UART1.
-+ *
-+ * We handle the IRQ according to _our_ priority which is:
-+ *
-+ * Highest ---- R4k Timer
-+ * Lowest ---- Combined hardware interrupt
-+ *
-+ * then we just return, if multiple IRQs are pending then we will just take
-+ * another exception, big deal.
