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.

If you say N, all options in this submenu will be skipped and disabled.

config VMGENID tristate "Virtual Machine Generation ID driver" default y help 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.
config FSL_HV_MANAGER tristate "Freescale hypervisor management driver" depends on FSL_SOC select EPAPR_PARAVIRT help 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.
