Subject: [PATCH 2/2] riscv: Annotate pgtable_l{4,5}_enabled with __ro_after_init
Date: Wed, 20 Mar 2024 14:47:12 +0800	[thread overview]
Message-ID: <20240320064712.442579-3-dawei.li@shingroup.cn> (raw)
In-Reply-To: <20240320064712.442579-1-dawei.li@shingroup.cn>

pgtable_l{4,5}_enabled are read only after initialization, make explicit
annotation of __ro_after_init on them.
