Provide the raw stsi 15,1,x data contents via debugfs. This makes it much easier to debug unexpected scheduling domains on machines that provide cpu topology information. Therefore this file adds a new 's390/stsi' debugfs directory with a file for each possible topology nesting level that is allowed by the architecture. The files will be created regardless if the machine supports all, or any, level. If a level is not supported, or no data is available, user space can recognize this with a -EINVAL error code when trying to read such data. In addition a 'topology' symlink is created that points to the file that contains the data that is used to create the scheduling domains.

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.
