Nicholas Piggin (1):
ring-buffer: speed up buffer resets by avoiding synchronize_rcu for each CPU

Steven Rostedt (VMware) (13):
tracing: Only allow trace_array_printk() to be used by instances
x86/ftrace: Make non direct case the default in ftrace_regs_caller
x86/ftrace: Only have the builtin ftrace_regs_caller call direct hooks
x86/ftrace: Do not jump to direct code in created trampolines
tracing: Move pipe reference to trace array instead of current_tracer
ring-buffer: Have nested events still record running time stamp
ring-buffer: Incorporate absolute timestamp into add_timestamp logic
ring-buffer: Add rb_time_t 64 bit operations for speeding up 32 bit
ring-buffer: Mark the !tail (crossing a page) as unlikely
ring-buffer: Consolidate add_timestamp to remove some branches
ring-buffer: Move the add_timestamp into its own function
ring-buffer: Call trace_clock_local() directly for RETPOLINE kernels
ring-buffer: Do not trigger a WARN if clock going backwards is detected

Wei Yang (4):
tracing: not necessary to undefine DEFINE_EVENT again
tracing: not necessary re-define DEFINE_EVENT_PRINT
tracing: define DEFINE_EVENT_PRINT not related to DEFINE_EVENT
tracing: not necessary to define DEFINE_EVENT_PRINT to be empty again
