This patchset is is prepared for the next 4.13 release for Linux/MIPS. It adds Loongson-3A R3 and Loongson's NMI handler support, adds a "model name" knob in /proc/cpuinfo which is needed by some userspace tools, improves I/O performance by IRQ balancing and IRQ affinity setting, fixes indexed scache flushing for Loongson-3, and introduces LOONGSON_LLSC_WAR to improve stability. V1 -> V2: 1, Add Loongson-3A R3 basic support. 2, Sync the code to upstream. V2 -> V3: 1, Add r4k_blast_scache_node for Loongson-3. 2, Update the last patch to avoid miscompilation. 3, Sync the code to upstream. V3 -> V4: 1, Support 4 packages in CPU Hwmon driver. 2, ICT is dropped in cpu name, and cpu name can be overwritten by BIOS. 3, Sync the code to upstream. V4 -> V5: 1, Drop some #ifdefs in the 2nd patch. 2, Improve maintainability of the 4th patch. 3, Sync the code to upstream. V5 -> V6: 1, Update commit message in the 2nd patch. 2, Drop #ifdefs and set irq_set_affinity() at runtime in the 6th patch. 3, Sync the code to upstream. V6 -> V7: 1, Fix bnez/beqz mistake in the last patch. 2, Sync the code to upstream. Huacai Chen(9): MIPS: Loongson: Add Loongson-3A R3 basic support. MIPS: c-r4k: Add r4k_blast_scache_node for Loongson-3. MIPS: Loongson: Add NMI handler support. MIPS: Loongson-3: Support 4 packages in CPU Hwmon driver. MIPS: Loongson-3: IRQ balancing for PCI devices. MIPS: Loongson-3: support irq_set_affinity() in i8259 chip. MIPS: Loogson: Make enum loongson_cpu_type more clear. MIPS: Add __cpu_full_name[] to make CPU names more human-readable. MIPS: Loongson: Introduce and use LOONGSON_LLSC_WAR.
