Subject: [PATCH 4.10 058/110] MIPS: Add MIPS_CPU_FTLB for Loongson-3A R2

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Huacai Chen <chenhc@...ote.com>

commit 033cffeedbd11c140952b98e8639bf652091a17d upstream.

Loongson-3A R2 and newer CPU have FTLB, but Config0.MT is 1, so add
MIPS_CPU_FTLB to the CPU options.
