Subject: [PATCH 0/3] arm64 live patching

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.
