A trivially copyable type provides a trivial copy constructor and a trivial copy assignment operator. This is enough for the runtime to memcpy the data to the device. Additionally there must be no virtual functions or virtual base classes and the destructor is guaranteed to be trivial, ie performs no action. The runtime does not require trivial default constructors because on alloc the memory is undefined. Thus, weaken the warning to be only issued if the mapped type is not trivially copyable.
