Subject: [PATCH 3/3] MIPS: Use memblock_add_node() in early_parse_mem() under CONFIG_NUMA
Date:   Fri, 18 Mar 2022 23:05:20 +0800
Message-Id: <1647615920-23103-4-git-send-email-yangtiezhu@loongson.cn>
In-Reply-To: <1647615920-23103-1-git-send-email-yangtiezhu@loongson.cn>
References: <1647615920-23103-1-git-send-email-yangtiezhu@loongson.cn>
Precedence: bulk

Use memblock_add_node to add new memblock region within a NUMA node
in early_parse_mem() under CONFIG_NUMA, otherwise the mem parameter
can not work well.
