Subject: [RFC PATCH v1 23/23] LoongArch: objtool: Mark non-standard object files and directories
Date:   Tue, 20 Jun 2023 16:18:32 +0800
Message-Id: <1687249112-2790-4-git-send-email-tangyouling@loongson.cn>
In-Reply-To: <1687249112-2790-1-git-send-email-tangyouling@loongson.cn>
References: <1687249112-2790-1-git-send-email-tangyouling@loongson.cn>
Precedence: bulk

Set OBJECT_FILES_NON_STANDARD for their related files and directories,
which will tell objtool to skip checking them.  It's ok to skip them
because they don't affect runtime stack traces.
