Virtual CPU hotplug support is being added across various architectures[1][3].
This series adds various code bits common across all architectures:

1. vCPU creation and Parking code refactor [Patch 1]
2. Update ACPI GED framework to support vCPU Hotplug [Patch 4,6,7]
3. ACPI CPUs AML code change [Patch 5]
4. Helper functions to support unrealization of CPU objects [Patch 8,9]
5. Misc [Patch 2,3]


Repository:
