The series consists of 3 parts: 1st: Implement ftrace with regs -- uses gcc-8's nop insertions to patch in ftrace calls. 2nd: "Classic" live patching infrastructure, as far as it's needed for backporting. 3rd: An attempt at reliable stack traces for the consistency model. I'm a bit uncertain whether the approach is correct. Torsten
