So there is already NOKPROBE_SYMBOL() macro to make a blacklist so that we can avoid such recursive faults. We need to identify such place and put the symbols in it as I did on x86.
Only if they are C functions. If they're assembly, NOKPROBE_SYMBOL() doesn't work. The answer there is to move them into a section that is excluded from kprobing. That's what the second patch I've already sent does.
