Subject: [PATCH 6/6] MIPS: loongson64: fix FTLB configuration
Date: Tue, 23 Nov 2021 15:49:27 +0800	[thread overview]
Message-ID: <20211123074927.12461-7-huangpei@loongson.cn> (raw)
In-Reply-To: <20211123074927.12461-1-huangpei@loongson.cn>

Commit "da1bd29742b1" makes 'set_ftlb_enable' called under
c->cputype unset, which leaves FTLB disabled on BOTH 3A2000
and 3A3000

Fixes: da1bd29742b1 ("MIPS: Loongson64: Probe CPU features via CPUCFG")
Signed-off-by: Huang Pei <huangpei@loongson.cn>
