To support full 64-bit addresses, there is a new field `ext_lfb_base` since Linux 4.1. It is unclear, however, how a loader is supposed to know if the kernel is compatible with this. Filling these previously reserved bits doesn't hurt, but an old kernel would probably ignore them and not know that it's handling a clipped, invalid address. So we play safe, and only allow 64-bit addresses for kernels after the 2.15 version bump of the boot protocol.
