Subject: [PATCH] powerpc: module: fix stubs for BE

From: Rusty Russell <[email-masked]>
Date: Mon, 12 May 2014 17:15:02 +0930

A simple patch which was supposed to swap r12 and r11 also
inexplicably changed the offset by two bytes.  This instruction
(to load r2) isn't used in LE, so it wasn't noticed.

Fixes: b1ce369e82 ("powerpc: modules: use r12 for stub jump address.)
