Subject: [PATCH v2 3/5] riscv: vmlinux.lds.S: explicitly catch .riscv.attributes sections
Date: Thu, 19 Jan 2023 23:54:15 +0800	[thread overview]
Message-ID: <20230119155417.2600-4-jszhang@kernel.org> (raw)
In-Reply-To: <20230119155417.2600-1-jszhang@kernel.org>

When enabling linker orphan section warning, I got warnings similar as
below:
riscv64-linux-gnu-ld: warning: orphan section `.riscv.attributes' from
`init/main.o' being placed in section `.riscv.attributes'

While I don't see any usage of .riscv.attributes sections' in kernel
now, just catch the sections so that we can enable linker orphan
section warning.
