Chris Wilson 8ffc024681 drm/i915: Defend against userspace creating a gem object with size==0 ... We currently only round up the userspace size to the next page. We assume that userspace hasn't made a mistake and requested a zero-length gem object and all through our internal code we then presume that every object is backed by at least a single page. Fix that oversight and report EINVAL back to userspace if they try to create a zero length object.
