mainlining shenanigans

MFN usually refers to "Machine Frame Number" in virtulization world. Currently GVT-g populates the shadow PPGTT/GGTT page table with MFN according to the translation between MFN and Guest PFN. When host IOMMU is enabled, GPU DMA transactions go through the IOMMU, GPU needs an IOVA<->MFN mapping to walk the shadow page table in host main memory. This patch will map a page in IOMMU page table before using it in shadow page table and release the map when a shadow page is going to be freed.

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.
