Subject: [PATCH] powerpc/boot: Specify ABI v2 when building an LE boot wrapper
Date: Tue, 15 Sep 2015 11:24:17 +1000 [thread overview]
Message-ID: <1442280257.9229.28.camel@kernel.crashing.org> (raw)
The kernel does it, not the boot wrapper, which breaks with some
cross compilers that still default to ABI v1.
Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
