Huacai Chen ef2f826c8f MIPS: Loongson-3: Enable the COP2 usage ... Loongson-3 has some specific instructions (MMI/SIMD) in coprocessor 2. COP2 isn't independent because it share COP1 (FPU)'s registers. This patch enable the COP2 usage so user-space programs can use the MMI/SIMD instructions. When COP2 exception happens, we enable both COP1 (FPU) and COP2, only in this way the fp context can be saved and restored correctly.
