Group the code this way so that we can avoid too many ifdef's: Data only used in an SNP VM with the paravisor; Functions only used in an SNP VM with the paravisor; Data only used in an SNP VM without the paravisor; Functions only used in an SNP VM without the paravisor; Functions only used in a TDX VM, with and without the paravisor; Functions used in an SNP or TDX VM, when the paravisor is present; Functions always used, even in a regular non-CoCo VM. No functional change.
