Yes, there's a xen_initial_domain() call in xen_efi_probe() which
would return false without this fix.

I'm not aware of this being an issue without the EFI code that I add
in patch 2, xen_domain_type would get set slightly later in the boot
process.

I guess both patches should be backported to 4.19 since that's the
only LTS release that has PVH dom0 support IIRC, and it would be good
to get this fixed.

Thanks, Roger.
