I assume it is safe for all device side compilations to ignore this attribute. Presumably device code uses fully general patterns to access global data that could live in any shared object. Most device ISAs are virtual anyway, it's not like they're going to use PC relative addressing to access this data, they'll have a full-width pointer somewhere / somehow. So, if there's an easy way to suppress the warning for device ISAs, that would be reasonable IMO.
