This document seems to be out of date for many, many years. Even it has misspelled from the first day. ARCH_HASH_SCHED_TUNE should be ARCH_HAS_SCHED_TUNE ARCH_HASH_SCHED_DOMAIN should be ARCH_HAS_SCHED_DOMAIN Since v2.6.14, kernel completely deleted the relevant code and even arch_init_sched_domains() was deleted. Right now, kernel is asking architectures to call set_sched_topology() to override the default sched domains. On the other hand, to print the schedule debug information, users need to set sched_debug cmdline or enable it by sysfs entry. So this patch also adds the description for sched_debug.

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.
