drm/i915: Introduce DRM_I915_GEM_MMAP_OFFSET This is really just an alias of mmap_gtt. The 'mmap offset' nomenclature comes from the value returned by this ioctl which is the offset into the device fd which userpace uses with mmap(2). mmap_gtt was our initial mmap_offset implementation, this extends our CPU mmap support to allow additional fault handlers that depends on the object's backing pages. Note that we multiplex mmap_gtt and mmap_offset through the same ioctl, and use the zero extending behaviour of drm to differentiate between them, when we inspect the flags. To support multiple mmap types on an object we need to support multiple mmap_offsets for an object (each offset in the global device address space corresponding to a unique instance of the object for a file + mmap type). As we drop the simplified drm core idea of a single mmap_offset, we need to provide replacement hooks for the dumb mmap interface as well.
