commit0e141d1c65upstream. The scmi-cpufreq driver calls the arch_set_freq_scale() callback on frequency changes to provide scale-invariant load-tracking signals to the scheduler. However, in the slow path, it does so while specifying the current and max frequencies in different units, hence resulting in a broken freq_scale factor. Fix this by passing all frequencies in KHz, as stored in the CPUFreq frequency table.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
