For a virtualized GPU, the host maintains the forcewake state on the real device. As we don't control forcewake ourselves, we can simply set force_wake_get() and force_wake_put() to be no-ops. By setting the vfuncs, we adjust both the manual control of forcewake and around the mmio accessors (making our vgpu specific mmio routines redundant and to be removed in the next patch).

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.
