Guys, I don't mind if you add new things that aren't enabled for other architectures, but please try to be a little more careful about breaking us. This patch results in the following on PowerPC: mv $i $i.orig && unifdef -DCONFIG_POWERPC -UCONFIG_X86 IA64 $i.orig > $i; [ $? -le 2 ] && rm $i.orig; done unifdef: can only do one file Here's my proposed fix: kvm: external module: Treat NONARCH_CONFIG as a list, not a single item.
