Subject: [PATCH v3 06/29] s390: Move RO_DATA into "text" PT_LOAD Program Header
Date: Tue, 29 Oct 2019 14:13:28 -0700 [thread overview]
Message-ID: <20191029211351.13243-7-keescook@chromium.org> (raw)
In-Reply-To: <20191029211351.13243-1-keescook@chromium.org>
In preparation for moving NOTES into RO_DATA, move 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.
