- For X64 CPUs, the PEI Services Table pointer is stored in the 8 bytes

- For Itanium and ARM CPUs, a the PEI Services Table Pointer is stored in
- a dedicated CPU register. This means that there is no memory storage
- associated with storing the PEI Services Table pointer, so no additional
- migration actions are required for Itanium or ARM CPUs.
