From: Anton Blanchard Date: Mon, 10 Mar 2014 10:06:12 +0000 (+1100) Subject: powerpc: Build little endian ppc64 kernel with ABIv2 X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=721aeaa9;p=deliverable%2Flinux.git powerpc: Build little endian ppc64 kernel with ABIv2 Build the little endian ppc64 kernel with ABIv2 if the toolchain supports it. We can identify an ABIv2 capable toolchain by the -mabi=elfv2 compiler flag.
