Linus Torvalds fe36bb8736 Tracing updates for 6.2:
- Add options to the osnoise tracer
   o panic_on_stop option that panics the kernel if osnoise is greater than some
     user defined threshold.
   o preempt option, to test noise while preemption is disabled
   o irq option, to test noise when interrupts are disabled
 
 - Add .percent and .graph suffix to histograms to give different outputs
 
 - Add nohitcount to disable showing hitcount in histogram output
 
 - Add new __cpumask() to trace event fields to annotate that a unsigned long
   array is a cpumask to user space and should be treated as one.
 
 - Add trace_trigger kernel command line parameter to enable trace event
   triggers at boot up. Useful to trace stack traces, disable tracing and take
   snapshots.
 
 - Fix x86/kmmio mmio tracer to work with the updates to lockdep
 
 - Unify the panic and die notifiers
 
 - Add back ftrace_expect reference that is used to extract more information in
   the ftrace_bug() code.
 
 - Have trigger filter parsing errors show up in the tracing error log.
 
 - Updated MAINTAINERS file to add kernel tracing  mailing list and patchwork
   info
 
 - Use IDA to keep track of event type numbers.
 
 - And minor fixes and clean ups
