Description

   The Set Fault Characteristic service sets the fault
   characteristics (for example, no execute) for the specified
   range of pages, checking that the specified mode is at least
   as privileged as the owner of the page.

   If the condition value SS$_ACCVIO is returned by this service, a
   value might not be returned in the memory locations pointed to by
   the return_va_64 and return_length_64 arguments.

   If a condition value other than SS$_ACCVIO is returned, the
   returned address and returned length indicate the pages that were
   successfully changed before the error occurred. If no pages were
   changed, the return_va_64 argument will contain the value -1, and
   a value might not be returned in the memory location pointed to
   by the return_length_64 argument.
