Now we are no longer dynamically allocating the GDT, we don't need the "cpu_gdt_table" at all: we can switch straight from "boot_gdt_table" to the per-cpu GDT. This means initializing the cpu_gdt array in C. The boot CPU uses the per-cpu var directly, then in smp_prepare_cpus() it switches to the per-cpu copy just allocated. For secondary CPUs, the early_gdt_descr is set to point directly to their per-cpu copy. For UP the code is very simple: it keeps using the "per-cpu" GDT as per SMP, but we never have to move.
