This patchset is prepared for the next 3.17 release for Linux/MIPS. In this series we add NUMA and Loongson-3B support. Multiple Loongson-3A chips can be interconnected with HT0-bus. This is a CC-NUMA system that every chip (node) has its own local memory and cache coherency is maintained by hardware. Loongson-3B is a 8-cores processor which looks like there are two Loongson-3A integrated in one chip: 8 cores are separated into two groups (two NUMA node). V1 -> V2: 1, Rework the first patch. 2, Use compat numa-related syscall for N32/O32 ABI. 3, Drop the patch "MIPS: Loongson: Make CPU name more clear". V2 -> V3: 1, Rebase the code for 3.17. 2, Reviewed by Andreas Herrmann. 3, Rework the patch "MIPS: Add NUMA support for Loongson-3". Huacai Chen(8): MIPS: Support hard limit of cpu count (nr_cpu_ids). MIPS: Support CPU topology files in sysfs. MIPS: Loongson: Modify ChipConfig register definition. MIPS: Add NUMA support for Loongson-3. MIPS: Add numa api support. MIPS: Add Loongson-3B support. MIPS: Loongson-3: Enable the COP2 usage. MIPS: Loongson: Rename CONFIG_LEMOTE_MACH3A to CONFIG_LOONGSON_MACH3X.
