Buffer objects need to be either pinned or reserved while a map is active, that's not the case here, so avoid caching the framebuffer map. This will cause increasing mapping activity mainly when we don't do page flipping. This fixes occasional garbage filled screens when the framebuffer has been evicted after the map. Since in-kernel mapping of whole buffer objects is error-prone on 32-bit architectures and also quite inefficient, we will revisit this later.

README
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.
