Hi, Ralf and Steve This adds several patches for Ftrace of MIPS, most of them are trivial cleanups, the last one fixes the useful set_graph_function interface provided by function graph tracer. The 1st two patches has been sent before, here just resend them. Thanks very much to Zhiping for reporting the set_graph_function problem.
