This is to make the x86 kprobe_ftrace_handler() more common so that
the code could be reused in future.  

While I agree with the change in general, I can't find anything which
reuses that code. So the change log is pretty useless and I have no idea
how this is related to the rest of the series.

In v1, this code is moved from x86 to common kprobes.c [1]
But I agree with Masami, consolidation could be done when arm64 kprobes
on ftrace is stable.

In v2, actually, the arm64 version's kprobe_ftrace_handler() is the same
as x86's, the only difference is comment, e.g

/* Kprobe handler expects regs->ip = ip + 1 as breakpoint hit */

while in arm64

/* Kprobe handler expects regs->pc = ip + 1 as breakpoint hit */


W/ above, any suggestion about the suitable change log?

Thanks
