Hi all, with gcc-8 now being out which includes the patchable-function-entries feature, I can now propose the live patching framework based on it. 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.
