/*
 *  The SI86DSCR subcommand of the sysi86() system call
 *  sets a segment or gate descriptor in the kernel.
 *  The following descriptor types are accepted:
 *    - executable and data segments in the LDT at DPL 3
 *    - a call gate in the GDT at DPL 3 that points to a segment in the LDT
 *  The request structure declared below is used to pass the values
 *  to be placed in the descriptor.  A pointer to the structure is
 *  passed as the second argument of the system call.
 *  If acc1 is zero, the descriptor is cleared.
