This fixes mmap() for fbdev devices by providing a custom implementation
based on the KMS variant. This is a fairly exotic case these days, hence
why it is not flagged for stable.
There is also support for dedicating one of the overlay planes to serve
as a hardware cursor on older Tegra that did support hardware cursors
but not RGBA formats for it.
Planes will now also export the IN_FORMATS property by supporting the
various block-linear tiling modifiers for RGBA pixel formats.
Other than that, there's a bit of cleanup of DMA API abuse, use of the
private object infrastructure for global state (rather than subclassing
atomic state objects) and an implementation of ->{begin,end}_cpu_access
callbacks for PRIME exported buffers, which allow users to perform cache
maintenance on these buffers.

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.
