This patchset is prepared for the next 4.21 release for Linux/MIPS. It add Loongson-3A R2.1 basic support, adds "model name" and "CPU MHz" knobs in /proc/cpuinfo which is needed by some userspace tools, adds Loongson-3 kexec/kdump support, 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. V2 -> V3: 1, Remove merged patches. 2, Improve code and descriptions (Thank James Hogan). 3, Sync the code to upstream.

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: Reserve extra memory for crash dump. MIPS: Loongson: Add kexec/kdump support. MIPS: Loongson: Introduce and use WAR_LLSC_MB.
