Since it handles physical address it should really be this. It's not like many drivers actually used it anyway. It shouldn't harm compatibility, drivers calling it with only 32bit would leave garbage in the higher bits but since on x86 it's a noop anyway, it would end up in the MSB register tha's ignored because it expects a 32bit result.
