3.16.7-ckt19 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
commit 655471f54c2e395ba29ae4156ba0f49928177cc1 upstream.
The kernel does it, not the boot wrapper, which breaks with some cross compilers that still default to ABI v1.
