Specification Reference:

• "docs/specs/acpi_cpu_hotplug.txt" in the QEMU source tree.

  The original (now "legacy") CPU hotplug interface appeared in QEMU v1.5.0. The new ("modern") hotplug interface appeared in QEMU v2.7.0.

  The macros in this header file map to the minimal subset of the modern interface that OVMF needs.
