Some stack dump fixes related to function_graph tracing.
Josh Poimboeuf (8):
ftrace: remove CONFIG_HAVE_FUNCTION_GRAPH_FP_TEST from config
ftrace: only allocate the ret_stack 'fp' field when needed
ftrace: add return address pointer to ftrace_ret_stack
ftrace: add ftrace_graph_ret_addr() stack unwinding helpers
x86/dumpstack/ftrace: convert dump_trace() callbacks to use
ftrace_graph_ret_addr()
ftrace/x86: implement HAVE_FUNCTION_GRAPH_RET_ADDR_PTR
x86/dumpstack/ftrace: mark function graph handler function as
unreliable
x86/dumpstack/ftrace: don't print unreliable addresses in
print_context_stack_bp()
