We will want to park GEM before disengaging the drive^W^W^W unwedging. Since we already do the work for idling, expose the guts as a new function that we can then reuse. v2: Just skip if already parked; makes it more forgiving to use by future callers. v3: Extract mark_busy, rename it to i915_gem_unpark and place it next to i915_gem_park so that we can evaluate it for symmetry more easily. Calling GEM from inside i915_request looks to be a bit of a layering violation, for the moment I am imaging them as being notify_cb.

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.
