When I was looking at the issue first time I thought in the same way. Though after some thinking I realized that it is perfectly valid to start 64-bit kernel from 32-bit bootloader which was build in 32-bit environment. So, I think it makes sense to take that patch, which is not very complicated and does not introduce anything which did not exist earlier in the relocator64.S, even a such scenario is not very common today.
