Linux scheduler allows architectures to assign capacity values to individual CPUs. This hints scheduler the performance difference between CPUs and allows more efficient task distribution them. Implement helper methods to set and get CPU capacities for s390. This is particularly helpful in vertical polarization configurations of LPARs. On vertical polarization an LPARs CPUs can get different polarization values depending on the CEC configuration. CPUs with different polarization values can perform different from each other, using CPU capacities this can be reflected to linux scheduler.

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 reStructuredText 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.
