Hello Jiri, while I do appreciate your work on the s390 architecture backend for livepatching: this should go upstream only via the s390 tree or with an Ack from Martin or me. That being said, what is the reason why module relocations are not supported? As far as I can tell right now there is only one simple in-kernel test case available (which is fine). However is the tool chain to generate additional livepatch modules, available somewhere? If so, where? Thanks, Heiko
