While running the kms_plane clipping test I noticed a similar problem to the one described in Display WA #1175. In this case, similarly for planes other than the cursor, with 1 or 3 pixels visible from the left edge of the screen to the end of the plane and an odd plane X offset used for clipping causes the same kind of underflow and display corruption as described for WA #1175. Fix this in a similar way as that WA rejecting planes ending <4 pixels from the left screen edge. v2: - Rebase on v2 of patch 1/1.

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.
