Subject: [PATCH 01/24] ARM64: Force LP64 to compile the kernel.
Date: Sat, 24 May 2014 00:01:22 -0700	[thread overview]
Message-ID: <1400914905-9594-2-git-send-email-apinski@cavium.com> (raw)
In-Reply-To: <1400914905-9594-1-git-send-email-apinski@cavium.com>

Sometimes the compiler is set to default to ILP32 ABI so we want to make sure the kernel can compile in that case.

Thanks,
Andrew Pinski
