This page fault handler helps GenieZone hypervisor to do demand paging. On a lower level translation fault, GenieZone hypervisor will first check the fault GPA (guest physical address or IPA in ARM) is valid e.g. within the registered memory region, then it will setup the vcpu_run->exit_reason with necessary information for returning to gzvm driver. With the fault information, the gzvm driver looks up the physical address and call the MT_HVC_GZVM_MAP_GUEST to request the hypervisor maps the found PA to the fault GPA (IPA). There is one exception, for protected vm, we will populate full VM's memory region in advance in order to improve performance.
