Hi Akashi,
Function graph tracer modifies a return address (LR) in a stack frame
to hook a function return. This will result in many useless entries
(return_to_handler) showing up in a stack tracer's output.
This patch replaces such entries with originals values preserved in
current->ret_stack[].

The following diff should be folded into this patch, not [7/7] one, to
address build breakage.
Thanks.
I fixed all the build errors reported by kbuild test robot.
