From 0b5e6661ac69983a54d9832ac33fd27d733306f8 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Mon, 23 Sep 2013 12:05:12 +1000 Subject: [PATCH] powerpc: Don't set HAVE_EFFICIENT_UNALIGNED_ACCESS on little endian builds POWER7 takes alignment exceptions on some unaligned addresses, so disable HAVE_EFFICIENT_UNALIGNED_ACCESS. This fixes an early boot issue in the printk code.
