Joel Fernandes 18cec7e0dd sched/fair: Remove impossible condition from find_idlest_group_cpu()
find_idlest_group_cpu() goes through CPUs of a group previous selected by
find_idlest_group(). find_idlest_group() returns NULL if the local group is the
selected one and doesn't execute find_idlest_group_cpu if the group to which
'cpu' belongs to is chosen. So we're always guaranteed to call
find_idlest_group_cpu() with a group to which 'cpu' is non-local.

This makes one of the conditions in find_idlest_group_cpu() an impossible one,
which we can get rid off.

README

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.
