- handle VCPUOP_register_vcpu_info and VCPUOP_get_physid (and add
respective layout checks)
- add missing structure size check for struct vcpu_info
- add missing layout check for vcpu_set_periodic_timer
- handle VCPUOP_set_singleshot_timer via argument translation as the
structure sizes differ (due to padding in 64-bits)
