AKASHI Takahiro fe13f95b72 arm64: pass a task parameter to unwind_frame() ... Function graph tracer modifies a return address (LR) in a stack frame to hook a function's return. This will result in many useless entries (return_to_handler) showing up in a call stack list. We will fix this problem in a later patch ("arm64: ftrace: fix a stack tracer's output under function graph tracer"). But since real return addresses are saved in ret_stack[] array in struct task_struct, unwind functions need to be notified of, in addition to a stack pointer address, which task is being traced in order to find out real return addresses. This patch extends unwind functions' interfaces by adding an extra argument of a pointer to task_struct.
