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

The davinci remoteproc driver is currently de-asserting the reset in its rproc .start() ops, but is not asserting the reset in its .stop() ops. This leaves the remote processor to not boot properly when using the sysfs 'state' variable between multiple start and stop operations. On the other hand, a reset is being asserted unconditionally in the driver remove function to alleviate some of these issues. Move this reset assertion logic into the .stop() ops implementation to fix the sysfs state-machine and the unbalanced reset. The logic from remove is still effective since .stop() ops will be invoked during the remove due to the enabled 'auto-boot' support. The probe already has support for asserting the reset in case the DSP is not in reset for some reason.

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.
