Note that because some registers reflect machine topology, all vcpus
should be created before this ioctl is invoked.
Userspace can call this function multiple times for a given vcpu, including
after the vcpu has been run. This will reset the vcpu to its initial
state. All calls to this function after the initial call must use the same
target and same set of feature flags, otherwise EINVAL will be returned.
Possible features:
- KVM_ARM_VCPU_POWER_OFF: Starts the CPU in a power-off state.
Depends on KVM_CAP_ARM_PSCI.
Depends on KVM_CAP_ARM_PSCI. If not set, the CPU will be powered on
and execute guest code when KVM_RUN is called.
- KVM_ARM_VCPU_EL1_32BIT: Starts the CPU in a 32bit mode.
Depends on KVM_CAP_ARM_EL1_32BIT (arm64 only).
- KVM_ARM_VCPU_PSCI_0_2: Emulate PSCI v0.2 for the CPU.

the system-level event type. The 'flags' field describes architecture
specific flags for the system-level event.
Valid values for 'type' are:
KVM_SYSTEM_EVENT_SHUTDOWN -- the guest has requested a shutdown of the
VM. Userspace is not obliged to honour this, and if it does honour
this does not need to destroy the VM synchronously (ie it may call
KVM_RUN again before shutdown finally occurs).
KVM_SYSTEM_EVENT_RESET -- the guest has requested a reset of the VM.
As with SHUTDOWN, userspace can choose to ignore the request, or
to schedule the reset to occur in the future and may call KVM_RUN again.
