[ Upstream commit29922fdfc2] If we take runnable_avg in max(runnable_avg, util_avg) in cpu_util(), we should then add or subtract task runnable_avg, but the arithmetic below is still with task util_avg. This mixes runnable_avg with util_avg which is incorrect. Fix by always doing arithmetic with runnable_avg and only take max(runnable_avg, util_avg) at the last step.

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.
