The _PPC change notifications from the platform firmware are per-CPU,
so acpi_processor_ppc_init() needs to add a frequency QoS request
for each CPU covered by a cpufreq policy to take all of them into
account.
Even though ACPI thermal control of CPUs sets frequency limits
per processor package, it also needs a frequency QoS request for each
CPU in a cpufreq policy in case some of them are taken offline and
the frequency limit needs to be set through the remaining online
ones (this is slightly excessive, because all CPUs covered by one
cpufreq policy will set the same frequency limit through their QoS
requests, but it is not incorrect).
Modify the code in accordance with the above observations.

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.
