| |
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).
v2: - As suggested by Mark, the commit logs for patch 4 and 5 were refined for easy review.
v1: https://lore.kernel.org/lkml/20220712021527.109921-1-lihuafei1@huawei.com/
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
