Yang Jihong f33052802e perf evlist: Add perf_evlist__go_system_wide() helper
commit f6ff1c7604 upstream.

For dummy events that keep tracking, we may need to modify its cpu_maps.

For example, change the cpu_maps to record sideband events for all CPUS.

Add perf_evlist__go_system_wide() helper to support this scenario.

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.
