[GIT PULL] tracing tooling: Updates for 6.5

[GIT PULL] tracing tooling: Updates for 6.5

[Steven Rostedt]

Linus,

[ As the merge window opened up while I was in Prague, I almost forgot
  about the tooling branch (even though I was also with Daniel who did
  all these changes!) ]

Tracing tooling updates for 6.5:

- Add cgroup support for rtla via the -C option

- Add --house-keeping option that tells rtla where to place the housekeeping
  threads.

- Have rtla/timerlat have its own tracing instance instead of using the top
  level tracing instance that is the default for other tracing users to use.

- Add auto analysis to timerlat_hist

- Have rtla start the tracers after creating the instances

- Reduce rtla hwnoise down to 75% from 100% as it runs with preemption disabled
  and can cause system instability at 100%.

- Add support to run timerlat_top and timerlat_hist threads in user-space
  instead of just using the kernel tasks.

- Some minor clean ups and documentation changes.
