* remotes/stefanha/tags/tracing-pull-request:
  monitor: Reduce handle_qmp_command() tracing overhead
  trace-events: fix code style: print 0x before hex numbers
  checkpatch: check trace-events code style
  trace-events: fix code style: %# -> 0x%
  coding_style: add point about 0x in trace-events
  trace: add trace_event_get_state_backends()
  trace: add TRACE_<event>_BACKEND_DSTATE()
  trace: ensure unique function / variable names per .stp file
  trace: ensure .stp files are rebuilt if trace tool source changes
