Because the cost of calling tick_nohz_get_sleep_length() may increase in the future, reorder the code in teo_select() so it first uses the statistics to pick up a candidate idle state and applies the utilization heuristic to it and only then calls tick_nohz_get_sleep_length() to obtain the sleep length value and refine the selection if necessary. This change by itself does not cause tick_nohz_get_sleep_length() to be called less often, but it prepares the code for subsequent changes that will do so. Signed-off-by: Rafael J.

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.
