After patch "drm: Use the same mmap-range offset and size for GEM and

enough for applications. Increase the drm mmap_range size to 1TB.
That change in size was accidental. Thanks for restoring the original
value. The fix will affect GEM as well. If that is not a problem then
Why even have an artificial restriction?
Well one possible explanation is that we somewhere need to allocate
memory to handle all that address space. E.g. when it is managed with a
radix or similar.
But as far as I remember there are only lists and r/b trees involved
here, so yeah doesn't make to much sense.
Anyway that is not the topic of this patch and it is Reviewed-by:
Christian König <christian.koenig@xxxxxxx> for now.
