Historically (before Linux 2.6.23), base_addr was unsigned long for
32-bit code and unsigned int for 64-bit code. In other words, it
was always a 32-bit value. When the ldt.h header files were
unified, the type became unsigned int on all systems. Update
modify_ldt.2 and set_thread_area.2 accordingly.
Indeed, on x86, the GDT and LDT specify 32-bit bases for code and
data segments, and this has nothing to do with the kernel.
