Subject: [PATCH 0/3] powerpc/ftrace: Enable HAVE_FUNCTION_GRAPH_RET_ADDR_PTR

Enable HAVE_FUNCTION_GRAPH_RET_ADDR_PTR for more robust stack unwinding 
when function graph tracer is in use. Convert powerpc show_stack() to 
use ftrace_graph_ret_addr() for better stack unwinding.

  powerpc/ftrace: Enable HAVE_FUNCTION_GRAPH_RET_ADDR_PTR
  powerpc: Use ftrace_graph_ret_addr() when unwinding
