+ Loongson-2K series chips, as the primary package interrupt controller which
can route local I/O interrupt to interrupt lines of cores.
+ Be aware of the following points.
+ 1.The Loongson-2K0500 is a single core CPU;
+ 2.The Loongson-2K0500/2K1000 has 64 device interrupt sources as inputs, so we

+ sources respectively.
