fr_ofs = layout.total_size;

That now needs updating, because we're no longer putting the return
code in that target_rt_frame_record.
Updated to
/*
* Reserve space for the standard frame unwind pair: fp, lr.
* Despite the name this is not a "real" record within the frame.
*/
I think the 'struct target_rt_frame_record' now does correspond
to the kernel's 'struct frame_record', right?
Yes.
