Another thing to consider for HVMlite is that if the 0 subarch (PC) is used in light of my linker table work and x86's use of it with the subarch and supported subarch bitmask, is that it would also mean HVMLite would run all routines currently pegged as needing PC type (the current KVM and bare metal path) and it would mean not running anything only pegged with Xen subarch type (but note that today Xen doesn't even set the subarch type). If there is nothing in common between PV and HVMlite (no x86 init calls to share), and if HVMLite *can* call *alllllllll* PC init calls, then by all means this is fine, and if we just need to distinguish stuff between PC types that's fine, it may still be possible to further extend hypervisor_type to the x86 init calls I'm adding as another supported_hyper_types to ensure even though a subarch is being used, that we also check the supported hypervisor type as well.
