This reverts commit cbed27cdf0e3f7ea3b2259e86b9e34df02be3fe4. As Andy Lutomirski observed: "I think this patch is bogus. pat_enabled() sure looks like it's supposed to return true if PAT is *enabled*, and these days PAT is 'enabled' even if there's no HW PAT support."

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.
