Subject: [PATCH 1/2] MIPS: Loongson64: Remove unused sysconf members
Date:   Thu,  4 Mar 2021 19:00:56 +0800
Message-Id: <20210304110057.22144-2-zhangqing@loongson.cn>
In-Reply-To: <20210304110057.22144-1-zhangqing@loongson.cn>
References: <20210304110057.22144-1-zhangqing@loongson.cn>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

We don't need them anymore, They are uniform on all Loongson64 systems
and have been fixed in DeviceTree.loongson3_platform_init is replaced
with DTS + driver.
