Subject: [RESEND PATCH 2/3] riscv: vdso.lds.S: merge .data section into .rodata section
Date: Tue, 12 Sep 2023 15:20:14 +0800	[thread overview]
Message-ID: <20230912072015.2424-3-jszhang@kernel.org> (raw)
In-Reply-To: <20230912072015.2424-1-jszhang@kernel.org>

The .data section doesn't need to be separate from .rodata section,
they are both readonly.
