- Add a 16-bit code and data segment to cstart.S. - Move ring 3 segment descriptors at the end of the GDT, and lay them out as required by syscall/sysret in cstart64.S. - Only define TSS_INTR for 32-bit, and place it where cstart64.S puts the 32-bit ring 0 segment. - Document that the same data segment can be used for 32 and 64-bit code. - Mark all descriptors as accessed.
