| |
This series mainly updates the ARM stack trace code to use the newer and simpler arch_stack_walk() interface. Two issues were fixed before that (see patch 1 and 2), as well as allowing stack_trace_save_tsk() to trace non-current tasks (see patch 3).
Li Huafei (5): ARM: stacktrace: Skip frame pointer boundary check for call_with_stack() ARM: stacktrace: Avoid duplicate saving of exception PC value ARM: stacktrace: Allow stack trace saving for non-current tasks ARM: stacktrace: Make stack walk callback consistent with generic code ARM: stacktrace: Convert stacktrace to generic ARCH_STACKWALK
