ACPI CPU Data initialization module
This module initializes the ACPI_CPU_DATA structure and registers the address
of this structure in the PcdCpuS3DataAddress PCD. This is a generic/simple
version of this module. It does not provide a machine check handler or CPU
register initialization tables for ACPI S3 resume. It also only supports the
number of CPUs reported by the MP Services Protocol, so this module does not
support hot plug CPUs. This module can be copied into a CPU specific package
and customized if these additional features are required.

UefiCpuPkg/CpuS3DataDxe: Add module to initialize ACPI_CPU_DATA for S3 This module initializes the ACPI_CPU_DATA structure and registers the address of this structure in the PcdCpuS3DataAddress PCD. This is a generic/simple version of this module. It does not provide a machine check handler or CPU register initialization tables for ACPI S3 resume. It also only supports the number of CPUs reported by the MP Services Protocol, so this module does not support hot plug CPUs. This module can be copied into a CPU specific package and customized if these additional features are required. This patch series is in response to the OvmfPkg patch series from Laszlo Ersek that enables SMM on OVMF.
