The Energy Model (EM) is going to support runtime modification. There are going to be 2 EM tables which store information. This patch aims to prepare the code to be generic and use one of the tables. The function will no longer get a pointer to 'struct em_perf_domain' (the EM) but instead a pointer to 'struct em_perf_state' (which is one of the EM's tables). Prepare em_pd_get_efficient_state() for the upcoming changes and make it possible to be re-used. Return an index for the best performance state for a given EM table. The function arguments that are introduced should allow to work on different performance state arrays. The caller of em_pd_get_efficient_state() should be able to use the index either on the default or the modifiable EM 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.
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.
