I thought about that, but in the end almost all in this patch is s390 specific stuff. Even the few common code files have "#ifdef __s390x__". Patches 2-7 are common code changes that are not 100% s390 specific. So what exactly is your suggestion for splitting up the patch? Or perhaps could you point me to the ppc or arm patches?
