This patchset is prepared for the next 4.16 release for Linux/MIPS. It add Loongson-3A R3.1 support, enable Loongson-3's SFB at runtime, adds "model name" and "CPU MHz" knobs in /proc/cpuinfo which is needed by some userspace tools, adds Loongson-3 kexec/kdump and CPUFreq support, fixes CPU UART irq delivery problem, and introduces WAR_LLSC_MB to improve stability. V1 -> V2: 1, Add Loongson-3A R3.1 basic support. 2, Fix CPU UART irq delivery problem. 3, Improve code and descriptions (Thank James Hogan). 4, Sync the code to upstream. Huacai Chen(12): MIPS: Loongson: Add Loongson-3A R3.1 basic support. MIPS: Loongson-3: Define and use some CP0 registers. MIPS: Loongson-3: Enable Store Fill Buffer at runtime. MIPS: c-r4k: Add r4k_blast_scache_node for Loongson-3. MIPS: Loongson fix name confict - MEM_RESERVED. MIPS: Ensure pmd_present() returns false after pmd_mknotpresent(). MIPS: Add __cpu_full_name[] to make CPU names more human-readable. MIPS: Align kernel load address to 64KB. MIPS: Loongson: Add kexec/kdump support. MIPS: Loongson: Make CPUFreq usable for Loongson-3. MIPS: Loongson-3: Fix CPU UART irq delivery problem. MIPS: Loongson: Introduce and use WAR_LLSC_MB.
