Subject: [PATCH] powerpc: compat: 32 bit little endian machine name is ppcle, not ppc
Date: Thu, 6 Mar 2014 16:10:11 +1100 [thread overview]
Message-ID: <20140306161011.4b6bd05b@kryten> (raw)
I noticed this when testing setarch. No, we don't magically
support a big endian userspace on a little endian kernel.
