Tested-by: Andy Lutomirski <l...@kernel.org> Now my test script panics for the right reason (init isn't actually an s390 binary). Thanks! I'll update my branch with the latest s390 DMA stuff, and now I can give it at least basic regression testing. Of course, I have to find a root filesystem, too. :) --Andy -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
