*Setup GDT as part of boot process*

Type: ``bool``

Help
====

This option sets up the GDT as part of the boot process. However,
this may conflict with some security scenarios where the GDT is
already appropriately set by an earlier bootloader stage, in which
case this should be disabled. If disabled, the global _gdt pointer
will not be available.
