Merge tag 'trace-tools-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing tools updates from Steven Rostedt:
- Add ':' to getopt option 'trace-buffer-size' in timerlat_hist for
consistency
- Remove unused sched_getattr define
- Rename sched_setattr() helper to syscall_sched_setattr() to avoid
conflicts
- Update counters to long from int to avoid overflow
- Add libcpupower dependency detection
- Add --deepest-idle-state to timerlat to limit deep idle sleeps
- Other minor clean ups and documentation changes
