This patchset is prepared for the next 3.20 release for Linux/MIPS. In this series we promote Loongson-3's ISA level to MIPS64R1 since it is not fully compatible with MIPS64R2. Multi-node DMA and coherent cache features are both added here. LEFI firmware interface is improved to make the kernel more generic (machtypes can be dropped). Besides, we add some basic platform drivers (GPIO, CPU Hwmon, ACPI init, oprofile, HPET and CPUFreq) for Loongson-3. V1 -> V2: 1, Add a patch to fix Loongson's CCA setting. 2, Rework the third patch. 3, Rebase the code for 3.19. V2 -> V3: 1, Remove patches which have merged in upstream. 2, Moving GPIO driver from arch/mips to drivers/gpio directory. 3, Optimize cacheflush by moving cpu_has_coherent_cache checking from local version to global version. V3 -> V4: 1, Don't build CPU Hwmon driver unconditionally. 2, Split the 2nd patch (Loongson GPIO driver) to two patches. V4 -> V5: 1, Cleanup Loongson-2F's GPIO driver before move to drivers/gpio. V5 -> V6: 1, Add perf support for Loongson-3. 2, Rebase the code for 3.20. V6 -> V7: 1, Rework the third and fifth patches.
