Extend the vmgenid platform driver to support devicetree bindings. With
this support, hypervisors can send vmgenid notifications to the virtual
machine without the need to enable ACPI. The bindings are located at:
Documentation/devicetree/bindings/rng/microsoft,vmgenid.yaml
Since this is no longer ACPI-dependent, remove the dependency from
Kconfig and protect the ACPI code with a single ifdef.

Say Y here to use the hypervisor-provided Virtual Machine Generation ID

to reseed the RNG when the VM is cloned. This is highly recommended if

you intend to do any rollback / cloning / snapshotting of VMs.

Prefer Y to M so that this protection is activated very early.

The Freescale hypervisor management driver provides several services
|
|
to drivers and applications related to the Freescale hypervisor:
|
|
|
|
1) An ioctl interface for querying and managing partitions.
|
|
|
|
2) A file interface to reading incoming doorbells.
|
|
|
|
3) An interrupt handler for shutting down the partition upon
|
|
receiving the shutdown doorbell from a manager partition.
|
|
|
|
4) A kernel interface for receiving callbacks when a managed
|
|
partition shuts down.
