Ilya Leoshkevich (1):
      ftrace: Expose call graph depth as unsigned int

Miaoqian Lin (1):
      tracing: Fix error handling in event_trigger_parse()

Steven Rostedt (27):
      tracing: Update function trace addresses with module addresses
      tracing: Show function names when possible when listing fields
      tracing: Only return an adjusted address if it matches the kernel address
      tracing: Adjust addresses for printing out fields
      tracing: Show preempt and irq events callsites from the offsets in field print
      tracing: Always use memcpy() in histogram add_to_key()
      tracing: Move histogram trigger variables from stack to per CPU structure
      tracing: Add common_comm to histograms
      ftrace: Show subops in enabled_functions
      ftrace: Comment that ftrace_func_mapper is freed with free_ftrace_hash()
      tracing/mmiotrace: Remove reference to unused per CPU data pointer
      ftrace: Do not bother checking per CPU "disabled" flag
      tracing: Just use this_cpu_read() to access ignore_pid
      tracing: Add tracer_tracing_disable/enable() functions
      tracing: Use tracer_tracing_disable() instead of "disabled" field for ftrace_dump_one()
      tracing: kdb: Use tracer_tracing_on/off() instead of setting per CPU disabled
      ftrace: Do not disabled function graph based on "disabled" field
      tracing: Do not use per CPU array_buffer.data->disabled for cpumask
      ring-buffer: Add ring_buffer_record_is_on_cpu()
      tracing: branch: Use trace_tracing_is_on_cpu() instead of "disabled" field
      tracing: Convert the per CPU "disabled" counter to local from atomic
      tracing: Use atomic_inc_return() for updating "disabled" counter in irqsoff tracer
      tracing: Remove unused buffer_page field from trace_array_cpu structure
      tracing: Rename event_trigger_alloc() to trigger_data_alloc()
      tracing: Remove unnecessary "goto out" that simply returns ret is trigger code
      tracing: Add a helper function to handle the dereference arg in verifier
      tracing: Allow the top level trace_marker to write into another instances

Tomas Glozar (1):
      tracing/osnoise: Allow arbitrarily long CPU string
