Subject: [PATCH 4.9 051/152] MIPS: Add MIPS_CPU_FTLB for Loongson-3A R2
Date: Mon, 10 Apr 2017 18:41:43 +0200 [thread overview]
Message-ID: <20170410164202.710367670@linuxfoundation.org> (raw)
In-Reply-To: <20170410164159.934755016@linuxfoundation.org>
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Huacai Chen <chenhc@lemote.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.
