Subject: [PATCH 3.11 087/182] powerpc/compat: 32-bit little endian machine name is ppcle, not ppc

3.11.10.9 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Anton Blanchard <anton@...ba.org>

commit 422b9b9684db3c511e65c91842275c43f5910ae9 upstream.

I noticed this when testing setarch. No, we don't magically
support a big endian userspace on a little endian kernel.
