[ Upstream commit 9e06d55f7b856bfaf82036b50072600b21e52d20 ] A frequent side comment has been to remove the use of writel_relaxed, readl_relaxed, and mb. This reduces driver complexity and the _relaxed variants were not known to provide any noticeable performance benefit.

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. 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.
