  38 ;
  39 ;       These are the fixed selector numbers for the GDT and LDT
  40 ;
  41 ;       All are declared with RPL = 0 so they can easily be used
  42 ;       as table indices.
  43 ;
  44 ;       Do not change anything without consulting files which include
  45 ;       this one. Add new selectors to the end and update the
  46 ;       gdt declaration and initialisation code elsewhere.
