Rafael J. Wysocki 4bb7f6c278 thermal: intel_powerclamp: Use first online CPU as control_cpu 
Commit 68b99e94a4 ("thermal: intel_powerclamp: Use get_cpu() instead
of smp_processor_id() to avoid crash") fixed an issue related to using
smp_processor_id() in preemptible context by replacing it with a pair
of get_cpu()/put_cpu(), but what is needed there really is any online
CPU and not necessarily the one currently running the code.  Arguably,
getting the one that's running the code in there is confusing.

For this reason, simply give the control CPU role to the first online
one which automatically will be CPU0 if it is online, so one check
can be dropped from the code for an added benefit.

README 

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.
