perf sched map supports cpu filter. However, even with cpu filters active, any context switch currently corresponds to a separate line. As result, context switches on irrelevant cpus result to redundant lines, which makes the output particlularly difficult to read on wide architectures. Fix it by skipping printing for irrelevant 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 reStructuredText 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.
