VMM use this interface to create vcpu instance which is a fd, and this
fd will be for any vcpu operations, such as setting vcpu registers and
accepts the most important ioctl GZVM_VCPU_RUN which requests GenieZone
hypervisor to do context switch to execute VM's vcpu context.

I'm almost certain that the arm64 maintainers will reject putting this 
here. What is the purpose of the split with drivers/virt/? Do you plan 
to support another arch in the near future?

Yes, there's KVM stuff in arch/arm64, but that is multi-arch.
