Adds in calls to allocate and release Trace ID for the CPUs in use by the perf session. Adds in notifier calls to the trace ID allocator that perf events are starting and stopping. This ensures that Trace IDs associated with CPUs remain the same throughout the perf session, and are only released when all perf sessions are complete.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
