Releasing shadow PPGTT pages is not enough when vGPU reset, the guest page table tracking data should has same life-cycle with all the shadow PPGTT pages; Otherwise there is no chance to re-shadow the PPGTT pages without free the guest page table tracking data. This patch clear the PPGTT reset logic and make the vGPU reset in working order. v2: refactor some logic to avoid code duplicated. v3: remove useless macro and add comments from Christophe. v4: keep reset logic in reset 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.
