+ Determines the new virtual address that is to be used on subsequent memory accesses.
+
+ For IA32, X64, and EBC, this service is a wrapper for the UEFI Runtime Service
+ ConvertPointer(). See the UEFI Specification for details.
+ For IPF, this function interprets Address as a pointer to an EFI_PLABEL structure
+ and both the EntryPoint and GP fields of an EFI_PLABEL are converted from physical
+ to virtiual addressing. Since IPF allows the GP to point to an address outside
+ a PE/COFF image, the physical to virtual offset for the EntryPoint field is used
+ to adjust the GP field. The UEFI Runtime Service ConvertPointer() is used to convert
+ EntryPoint and the status code for this conversion is always returned. If the convertion
+ of EntryPoint fails, then neither EntryPoint nor GP are modified. See the UEFI
+ Specification for details on the UEFI Runtime Service ConvertPointer().
+
+ @param DebugDisposition Supplies type information for the pointer being converted.
+ @param Address The pointer to a pointer that is to be fixed to be the
+ value needed for the new virtual address mapping being
+ applied.
