This is what I've been trying to do for HVMlite/PVHv2 guests. Roger and
I have a PoC toolstack code that loads limited ACPI data into the guest
but I wonder whether these patches already do this.
I haven't gone over the series in detail yet. Does this allow toolstack
to load RSDP and then R/XSDT, FADT etc. directly to guest memory or are
they passed to hvmloader to do so via hvm_start_info? (I think it's the
latter based on how I read patch 13 but I am not sure).
