Yes of course, I knew most of it was architecture independant but I delayed
this TODO for future ports, and you've done it.

Thanks.

Just a micro detail: the ftrace_push/pop_return_trace are parts of
the core of the entry/return probe, something that could be used
by other users than the function graph tracer itself.

Perhaps it would be better to put them in kernel/trace/ftrace.c
What do you think?
