[GIT PULL] tracing latency: Updates for 7.2

[Steven Rostedt]

Linus,

tracing latency updates for 7.2:

- Dump the stack to the buffer on timerlat uret threashold event

  Record the stack trace in the buffer for THREAD_URET as well as
  THREAD_CONTEXT when the threshold is hit. Otherwise, if the threshold was
  not hit at task wakeup, but was at task return, it will not produce a
  stack trace making it harder to debug.

- Have osnoise trace prints print to all buffers

  The osnoise tracer is allowed to print to the main buffer. Add a
  osnoise_print() helper function and use trace_array_vprintk() to print
  osnoise output.
