Minimal supplement to upstream Kernel Self Protection Project changes. Features already provided by SELinux + Yama and archs other than multiarch arm64 / x86_64 aren't in scope. Only tags have stable history. Shared IRC channel with KSPP: irc.libera.chat #linux-hardening

When the governor is set to "performance", intel_pstate does not need the scheduler hook for doing any calculations. Under these conditions, its only purpose is to continue to maintain cpufreq/scaling_cur_freq. The cpufreq/scaling_cur_freq sysfs attribute is now provided by shared x86 cpufreq code on modern x86 systems, including all systems supported by the intel_pstate driver. So in "performance" governor mode, the scheduler hook can be skipped. This applies to both in Software and Hardware P-state control modes.

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.
