OK, but that's an early GDT used during boot, which shouldn't have any
bearing on the GDT of the running kernel.
I can't imagine a reason why you'd want to do this.
I'm looking at packing all the descriptors together so they share a
cache line, and therefore reduce the likelihood of a cache miss when
loading a segment register.
