Subject: [PATCH v6 5/6] powerpc/64: Make COMPAT user-selectable disabled on littleendian by default.
Date:   Fri, 30 Aug 2019 20:57:56 +0200
Message-Id: <a4704404cccb801457aab577781001b28c495233.1567188299.git.msuchanek@suse.de>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

On bigendian ppc64 it is common to have 32bit legacy binaries but much
less so on littleendian.
