Hello Andrew, I had a long discussion with Vivek Goyal on the s390 kdump support (thanks Vivek for all the time!). As a result of this, here are two common code patches that are required for the s390 port. Could you please integrate them upstream in the next merge window? The s390 specific part will be integrated by our s390 maintainer Martin Schwidefsky. I will be on vacation for the next two weeks. Therefore if you have comments or questions, please contact also Martin Schwidefsky and Heiko Carstens. Thanks Michael
