Subject: [PATCH v13 06/11] arm64: Use stack_trace_consume_fn and rename args to unwind()

From: "Madhavan T. Venkataraman" <madvenka@...ux.microsoft.com>

Rename the arguments to unwind() for better consistency. Also, use the
typedef stack_trace_consume_fn for the consume_entry function as it is
already defined in linux/stacktrace.h.
