[GIT PULL] tracing/rtla: Updates to the RTLA tool

[Steven Rostedt]

Linus,

I'm sending this as a separate pull request from my normal tracing tree, as
it had dependencies to commits in your tree but not in my development
branch. As it only affects the tools/ directory, I kept it separate as it
has no changes to the kernel itself.

Real Time Linux Analysis Tool updates for 5.18

Changes to RTLA:

 - Support for adjusting tracing_threashold

 - Add -a (auto) option to make it easier for users to debug in the field

 - Add -e option to add more events to the trace

 - Add --trigger option to add triggers to events

 - Add --filter option to filter events

 - Add support to save histograms to the file

 - Add --dma-latency to set /dev/cpu_dma_latency

 - Other fixes and cleanups

Please pull the latest trace-rtla-v5.18 tree, which can be found at:
