In preparation for changes that would otherwise require adding a new level of indentation to the while(sd) loop, create a new function find_idlest_cpu() which contains this loop, and rename the existing find_idlest_cpu() to find_idlest_group_cpu(). Code inside the while(sd) loop is unchanged. @new_cpu is added as a variable in the new function, with the same initial value as the @new_cpu in select_task_rq_fair().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
