1157 + *
1158 + * 1) We handle one interrupt and return, sitting in a loop and moving across
1159 + * all the pending IRQ bits in the cause register is _NOT_ the answer, the
1160 + * common case is one pending IRQ so optimize in that direction.
1161 + *
1162 + * 2) We need not check against bits in the status register IRQ mask, that
1163 + * would make this routine slow as hell.
1164 + *
1165 + * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in
1166 + * between like BSD spl() brain-damage.
1167 + *
1168 + * Furthermore, the IRQs on the MIPS board look basically (barring software
1169 + * IRQs which we don't use at all and all external interrupt sources are
1170 + * combined together on hardware interrupt 0 (MIPS IRQ 2)) like:
1171 + *
1172 + * MIPS IRQ Source
1173 + * -------- ------
1174 + * 0 Software (ignored)
1175 + * 1 Software (ignored)
1176 + * 2 Combined hardware interrupt (hw0)
1177 + * 3 Hardware (ignored)
1178 + * 4 Hardware (ignored)
1179 + * 5 Hardware (ignored)
1180 + * 6 Hardware (ignored)
1181 + * 7 R4k timer (what we use)
1182 + *
1183 + * Note: On the SEAD board thing are a little bit different.
1184 + * Here IRQ 2 (hw0) is wired to the UART0 and IRQ 3 (hw1) is wired
1185 + * wired to UART1.
1186 + *
1187 + * We handle the IRQ according to _our_ priority which is:
1188 + *
1189 + * Highest ---- R4k Timer
1190 + * Lowest ---- Combined hardware interrupt
1191 + *
1192 + * then we just return, if multiple IRQs are pending then we will just take
1193 + * another exception, big deal.
