Merge tag 'trace-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt: "No new features this release. Mostly clean ups, restructuring and documentation. - Have ftrace_bug() show ftrace errors before the WARN, as the WARN will reboot the box before the error messages are printed if panic_on_warn is set. - Have traceoff_on_warn disable tracing sooner (before prints) - Write a message to the trace buffer that its being disabled when disable_trace_on_warning() is set. - Separate out synthetic events from histogram code to let it be used by other parts of the kernel. - More documentation on histogram design. - Other small fixes and clean ups" * tag 'trace-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Remove obsolete PREEMPTIRQ_EVENTS kconfig option tracing/doc: Fix ascii-art in histogram-design.rst tracing: Add a trace print when traceoff_on_warning is triggered ftrace,bug: Improve traceoff_on_warn selftests/ftrace: Distinguish between hist and synthetic event checks tracing: Move synthetic events to a separate file tracing: Fix events.rst section numbering tracing/doc: Fix typos in histogram-design.rst tracing: Add hist_debug trace event files for histogram debugging tracing: Add histogram-design document tracing: Check state.disabled in synth event trace functions tracing/probe: reverse arguments to list_add tools/bootconfig: Add a summary of test cases and return error ftrace: show debugging information when panic_on_warn set
