Laszlo Ersek 38ee7bafa7 UefiCpuPkg/CpuS3DataDxe: do not allocate useless register tables ... CpuS3DataDxe allocates the "RegisterTable" and "PreSmmInitRegisterTable" arrays in ACPI_CPU_DATA just so every processor in the system can have its own empty register table, matched by APIC ID. This has never been useful in practice. Given commit e992cc3f48 ("UefiCpuPkg PiSmmCpuDxeSmm: Reduce SMRAM consumption in CpuS3.c", 2021-01-11), simply leave both "AcpiCpuData->RegisterTable" and "AcpiCpuData->PreSmmInitRegisterTable" initialized to the zero address. This simplifies the driver, and saves both normal RAM (boot services data type memory) and -- in PiSmmCpuDxeSmm -- SMRAM.
