Subject: [PATCH v4 4/4] powerpc/64: Make COMPAT user-selectable disabled on littleendian by default.
Date: Thu, 29 Aug 2019 12:23:43 +0200 [thread overview]
Message-ID: <eebe34a56c97b97d852779cbfbb35bdd3d8ba44d.1567072270.git.msuchanek@suse.de> (raw)
In-Reply-To: <cover.1567072270.git.msuchanek@suse.de>
On bigendian ppc64 it is common to have 32bit legacy binaries but much
less so on littleendian.
Signed-off-by: Michal Suchanek <msuchanek@suse.de>
