Subject: [PATCH v7 5/6] powerpc/64: Make COMPAT user-selectable disabled on littleendian by default.
Date: Fri, 30 Aug 2019 23:03:42 +0200 [thread overview]
Message-ID: <c7c88e88408588fa6fcf858a5ae503b5e2f4ec0b.1567198492.git.msuchanek@suse.de> (raw)
In-Reply-To: <cover.1567198491.git.msuchanek@suse.de>
On bigendian ppc64 it is common to have 32bit legacy binaries but much
less so on littleendian.
