Subject: [PATCHv6 4/4] arm64: Add build salt to the vDSO
Date:   Thu,  5 Jul 2018 17:49:40 -0700
Message-Id: <20180706004940.32587-5-labbott@redhat.com>
In-Reply-To: <20180706004940.32587-1-labbott@redhat.com>
References: <20180706004940.32587-1-labbott@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The vDSO needs to have a unique build id in a similar manner
to the kernel and modules. Use the build salt macro.
