In-Reply-To: <1400914939-9708-1-git-send-email-apinski@cavium.com> References: <1400914939-9708-1-git-send-email-apinski@cavium.com> Message-ID: <1400914939-9708-2-git-send-email-apinski@cavium.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Sometimes the compiler is set to default to ILP32 ABI so we want to make sure the kernel can compile in that case.
