Subject: [PATCH 0/5] ARM: Convert to ARCH_STACKWALK
Date: Tue, 12 Jul 2022 10:15:22 +0800 [thread overview]
Message-ID: <20220712021527.109921-1-lihuafei1@huawei.com> (raw)
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
