I've dropped stable, something this big needs to get some wider testing before
it goes to stable.
It was also giving me:
arch/powerpc/boot/opal.c:30:12: warning: âopal_con_openâ defined but not
used [-Wunused-function]
So I applied the following patch to fix it:
diff --git a/arch/powerpc/boot/opal.c b/arch/powerpc/boot/opal.c
