Yang Jihong e024e98e81 perf evlist: Add evlist__findnew_tracking_event() helper 
[ Upstream commit 9c95e4ef06 ]

Currently, intel-bts, intel-pt, and arm-spe may add tracking event to the
evlist. We may need to search for the tracking event for some settings.

Therefore, add evlist__findnew_tracking_event() helper.

If system_wide is true, evlist__findnew_tracking_event() set the cpu map
of the evsel to all online CPUs.

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.
