Subject: [PATCHv6 3/4] powerpc: Add build salt to the vDSO
Date: Thu, 5 Jul 2018 17:49:39 -0700 [thread overview]
Message-ID: <20180706004940.32587-4-labbott@redhat.com> (raw)
In-Reply-To: <20180706004940.32587-1-labbott@redhat.com>
The vDSO needs to have a unique build id in a similar manner
to the kernel and modules. Use the build salt macro.
