Subject: [PATCH 06/29] s390: Move RO_DATA into "text" PT_LOAD Program Header
Date:   Thu, 26 Sep 2019 10:55:39 -0700
Message-Id: <20190926175602.33098-7-keescook@chromium.org>
In-Reply-To: <20190926175602.33098-1-keescook@chromium.org>
References: <20190926175602.33098-1-keescook@chromium.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In preparation for moving NOTES into RO_DATA, this moves RO_DATA back
into the "text" PT_LOAD Program Header, as done with other
architectures. The "data" PT_LOAD now starts with the writable data
section.
