From a774e70e50f898c7380f6cfb368d55a99ed71956 Mon Sep 17 00:00:00 2001
From: Andrew Pinski <apinski@cavium.com>
Date: Wed, 3 Sep 2014 14:18:55 -0700
Subject: [PATCH 01/25] ARM64: Force LP64 to compile the kernel
Sometimes the compiler is set to default to ILP32 ABI so we want to make sure the kernel can compile in that case.
