Subject: [RFCv2 PATCH 3/3] x86/vdso: Add build salt to the vDSO
Date:   Thu, 29 Mar 2018 11:01:12 -0700
Message-Id: <20180329180112.11055-4-labbott@redhat.com>
In-Reply-To: <20180329180112.11055-1-labbott@redhat.com>
References: <20180329180112.11055-1-labbott@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The vDSO is linked separately from the kernel and modules. Ensure it picks
up the comment section, if available.
