Loading multiboot ELF kernels linked to high addresses |

Hi,
I have a multiboot kernel linked at a high address (0xC0100000) but
loaded at a reasonable address (0x100000), when the kernel boots I can
usually access global variables even though they are genuinely linked
above 3GB.
Does grub setup a GDT to allow this to work, or is my code somehow
accessing globals using local offsets?
Any help would be appreciated.
