[PATCH 3.10 14/48] powerpc/compat: 32-bit little endian machine name is ppcle, not ppc

From: Greg Kroah-Hartman
Date: Sun May 11 2014 - 15:53:46 EST


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

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

From: Anton Blanchard <anton@xxxxxxxxx>

commit 422b9b9684db3c511e65c91842275c43f5910ae9 upstream.

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