[ QUESTION] How to manually do VM exit in the guest?

[Le__Nam]

I need to define a new exit reason of my own and want to set the exit reason in VMCS before switching to the host KVM module,then do something in KVM hypervisor for this reason.But I notice the vmcs_writel() is static,how can I do it?

THANKS
