[Qemu-devel] [RFC v3 02/15] hw/boards: Add a MachineState parameter to kvm_type callback

[Eric Auger <eric.auger@redhat.com>]

On ARM, the kvm_type will be resolved by querying the KVMState.
Let's add the MachineState handle to the callback so that we
can retrieve the  KVMState handle. in kvm_init, when the callback
is called, the kvm_state variable is not yet set.
