Add support for the dma-buf exporter role to the frame buffer API. The importer role isn't meaningful for frame buffer devices, as the frame buffer device model doesn't allow using externally allocated memory. taken from an RFC on the linaro-mm-sig mailing list: http://lists.linaro.org/pipermail/linaro-mm-sig/2012-June/002167.html Fixes by Mark Yao: add FBIOGET_DMABUF to compat_ioctl.

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.
