Ian Rogers 493902fcbd perf completion: Support completion of libpfm4 events
Use `perf list --raw-dump pfm` to support completion of libpfm4 events.

Committer testing:

  # grep -m1 'model name' /proc/cpuinfo
  model name	: AMD Ryzen 9 5950X 16-Core Processor

Before:

  Files in the current directory are expanded when <tab>

After:

  Only the PFM events are:

  # . tools/perf/perf-completion.sh
  # perf stat --pfm-events <tab>

Becomes:

  # perf stat --pfm-events perf_raw::r0000

As apparently there are no other PFM events for this Ryzen 9 5950X
machine.

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.
