Len Brown 1c7c7388e6 tools/power turbostat: Clustered Uncore MHz counters should honor show/hide options
The clustered uncore frequency counters, UMHz*.*
should honor the --show and --hide options.

All non-specified counters should be implicityly hidden.
But when --show was used, UMHz*.* showed up anyway:

$ sudo turbostat -q -S --show Busy%
Busy%  UMHz0.0  UMHz1.0  UMHz2.0  UMHz3.0  UMHz4.0

Indeed, there was no string that can be used to explicitly
show or hide clustered uncore counters.

Even through they are dynamically probed and added,
group the clustered UMHz*.* counters with the legacy
built-in-counter "UncMHz" for show/hide.

turbostat --show Busy%
	does not show UMHz*.*.
turbostat --show UncMHz
	shows either UncMHz or UMHz*.*, if present
turbostat --hide UncMHz
	hides either UncMHz or UMHz*.*, if present

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.
