Because PrepareApStartupVector() stores StackAddress to
"mExchangeInfo->StackStart" (which has type (VOID*)), and because
"UefiCpuPkg/PiSmmCpuDxeSmm/X64/MpFuncs.nasm" reads the latter with:
add edi, StackStartAddressLocation
add rax, qword [edi]
mov rsp, rax
mov qword [edi], rax
in long-mode code. So code can remove below 4G limitation.
