Hi all,
Today's linux-next build (powerpc_ppc64_defconfig) produced lots of
warnings like this:
In file included from arch/powerpc/platforms/powermac/smp.c:24:
include/linux/kernel.h:498:1: warning: "BUILD_BUG_ON" redefined
In file included from include/linux/linkage.h:4,
from include/linux/kernel.h:11,
from arch/powerpc/platforms/powermac/smp.c:24:
include/linux/compiler.h:209:1: warning: this is the location of the previous definition
Introduced by commit 3cff9a338bd3ace9cfb501e08aeb69913b47c53d ("manual
merge of core/debug") which recreated the definition of the BUILD_BUG_ON
macro in kernel.h.
I applied the following patch.
