241  cpu等于These macros fold the SMP functionality into a single CPU system()
242  restore等于0
245  native_store_gdt( & gdt)
246  fixmap_gdt等于Provide the fixmap address of the remapped GDT
252  如果address恒等于fixmap_gdt则
253  Load the original GDT from the per-cpu structure
254  restore等于1
256  asm volatile
257  如果restore则Load a fixmap remapping of the per-cpu GDT
