The patch looks ok, a few remarks however: - you include the full head.S in the patch whereas you most likely just added the empty mcount; - I see no patch of any Kconfig, did you forget them ? - the arm_return_address function seem to rely on frame pointers, so should not the tracer option require the CONFIG_FRAME_POINTER option to be enabled ? -- Gilles Chanteperdrix
