[PATCH 0/3] arm64: Convert to ARCH_STACKWALK

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.

Mark Brown (3):
stacktrace: Remove reliable argument from arch_stack_walk() callback
arm64: stacktrace: Make stack walk callback consistent with generic
code
arm64: stacktrace: Convert to ARCH_STACKWALK
