Subject: i915 utils: range_overflows*()

Hi Kees -

drivers/gpu/drm/i915/i915_utils.h has a handful of helper macros for
checking range overflows: range_overflows(), range_overflows_t(),
range_overflows_end(), and range_overflows_end_t().

Looks like the first one has also been copy-pasted to
include/drm/drm_buddy.h.

Feels like include/linux/overflow.h would be the right place for (some
version of) them.

Thoughts?

BR,
Jani.
