Disables/enables XD (eXecute Disable) bit.
NOTE: The XD bit is a technology used in to separate areas of memory for use by either storage
of processor instructions or code or for storage of data. Memory designated with the NX attribute
may only be used for storing data. Processor instructions should not reside and cannot be executed
there. This technology is used to prevent buffer overflow attacks – malicious software that takes over
computers by inserting code into another program's data storage area and running that code.
