Subject: [GIT PULL] tracing/tools: Updates for 6.3


Linus,

Tracing tools updates for 6.3:

- Use total duration to calculate average in rtla osnoise_hist

- Use 2 digit precision for displaying average

- Print an intuitive auto analysis of timerlat results

- Add auto analysis to timerlat top

- Add hwnoise, which is the same as osnoise but focuses on hardware

- Small clean ups
