[PATCH V7 0/9] MIPS: Loongson: feature and performance improvements

[Huacai Chen <chenhc@lemote.com>]

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.

 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.
