If the only pre-selected candidate CPU in find_energy_efficient_cpu() happens to be prev_cpu, there is not point in computing the system energy since we have nothing to compare it against, so we currently bail out early. The same logic can be extended when prefer_idle tasks are routed in the energy-aware wake-up path: if the only candidate is idle for a prefer_idle task, just select it no matter what the energy impact is. That should help speeding-up wake-ups of prefer_idle tasks, at least when find_best_target() is used for them.

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.
