This patchset is is prepared for the next 4.14 release for Linux/MIPS. It 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 pmd_present() and indexed scache flushing for Loongson-3, and introduces WAR_LLSC_MB to improve stability. Huacai Chen(8): MIPS: Loongson-3: Enable Store Fill Buffer at runtime. MIPS: c-r4k: Add r4k_blast_scache_node for Loongson-3. 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: Introduce and use WAR_LLSC_MB.
