Does the attached patch seem valid ? Feedback from s390 > and powerpc users who use this functionality would be appreciated. On S390 we use the hypercall interface with characters instead of memory addresses as parameters. The hypervisor then decides if the character is an early printk or a real hypercall. I'm not sure how PPC handles that - I never used virtio console there. Either way, early printk does work for S390. So what exactly is this patch supposed to fix?
