• Robustify the user backtrace code, as done on other architectures.

Big thanks to Steve Capper for the help in debugging and rephrasing the commits descriptions.

Stress tested with perf record and tracepoints triggering (-e <tracepoint>), with unwinding using fp (--call-graph fp) and dwarf info (--call-graph dwarf).

I've taken the first two in this series, but patch 3 still doesn't address my concerns about saving the required register state for unwinding.

Thanks!
