    Subject[PATCH 3.12 135/182] powerpc/compat: 32-bit little endian machine name is ppcle, not ppc
    Date
    From: Anton Blanchard <anton@samba.org>

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

    ===============

    commit 422b9b9684db3c511e65c91842275c43f5910ae9 upstream.

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