GVT may receive partial write on one guest PTE update. Validate gfn not to translate incomplete gfn. This avoids some unnecessary error messages incurred by the incomplete gfn translating. Also fix the bug that the whole PPGTT shadow page update is aborted on any invalid gfn entry. gfn validation relys on hypervisor's help. Add one MPT module function to provide the function.

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.
