Summary: (Actually writing a 64-bit pointer in 32-bit chunks is normally a bad idea when that value is continuously used, but given that the kernel’s __TEXT segment is a lot smaller than 0x100000000 , we can once more leave the top 32 bits untouched and just swap out the bottom half, which happens in a single step.)
