Peter Anvin" Cc: Christian Borntraeger , Ingo Molnar , Jiri Slaby , x86@kernel.org, linux-arm-kernel@lists.infradead.org, linux-s390@vger.kernel.org, linux-kernel@vger.kernel.org, Mark Brown This series updates the arm64 stacktrace code to use the newer and much simpler arch_stack_walk() interface, the main benefit being a single entry point to the arch code with no need for the arch code to worry about skipping frames. Along the way I noticed that the reliable parameter to the arch_stack_walk() callback appears to now be redundant so there's also a patch here removing that from the existing code to simplify the interface. This depends on 0de674afe83cb2367 (arm64: stacktrace: Move export for save_stack_trace_tsk()) due to the code that was fixed there being removed.
