    kernel - Expand GDT table to maximum size
    
    * Expand the GDT table from 9 entries to 65536 entries
      (limit field 0xFFFF).
    
    * This deals with an Intel quirk in VMX where the descriptor for the
      GDT limit field is not restored on a VM exit, but instead
      unconditionally set to 0xFFFF.
