[PATCH 0/3] ARM: perf: allow tracing with kernel tracepoints events

- Robustify the user backtrace code, as done on other architectures. - Provide the symbols resolution when triggering from tracepoints.

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