Merge tag 'trace-v4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt: "This is mostly clean ups and small fixes. Some of the more visible changes are: - The function pid code uses the event pid filtering logic - [ku]probe events have access to current->comm - trace_printk now has sample code - PCI devices now trace physical addresses - stack tracing has less unnessary functions traced" * tag 'trace-v4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: printk, tracing: Avoiding unneeded blank lines tracing: Use __get_str() when manipulating strings tracing, RAS: Cleanup on __get_str() usage tracing: Use outer () on __get_str() definition ftrace: Reduce size of function graph entries tracing: Have HIST_TRIGGERS select TRACING tracing: Using for_each_set_bit() to simplify trace_pid_write() ftrace: Move toplevel init out of ftrace_init_tracefs() tracing/function_graph: Fix filters for function_graph threshold tracing: Skip more functions when doing stack tracing of events tracing: Expose CPU physical addresses (resource values) for PCI devices tracing: Show the preempt count of when the event was called tracing: Add trace_printk sample code tracing: Choose static tp_printk buffer by explicit nesting count tracing: expose current->comm to [ku]probe events ftrace: Have set_ftrace_pid use the bitmap like events do tracing: Move pid_list write processing into its own function tracing: Move the pid_list seq_file functions to be global tracing: Move filtered_pid helper functions into trace.c tracing: Make the pid filtering helper functions global
