+#  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.
