Subject: [PATCH v4 4/4] arm64: vdso32: enable orphan handling for VDSO
Date: Thu, 14 Apr 2022 11:46:11 +0100 [thread overview]
Message-ID: <20220414104611.17748-5-joey.gouly@arm.com> (raw)
In-Reply-To: <20220414104611.17748-1-joey.gouly@arm.com>
Like vmlinux, enable orphan-handling for the compat VDSO32. This can catch
subtle errors that might arise from unexpected sections being included.
