Joao Martins b3e6982b41 i386/pc: restrict AMD only enforcing of 1Tb hole to new machine type ... The added enforcing is only relevant in the case of AMD where the range right before the 1TB is restricted and cannot be DMA mapped by the kernel consequently leading to IOMMU INVALID_DEVICE_REQUEST or possibly other kinds of IOMMU events in the AMD IOMMU. Although, there's a case where it may make sense to disable the IOVA relocation/validation when migrating from a non-amd-1tb-aware qemu to one that supports it. Relocating RAM regions to after the 1Tb hole has consequences for guest ABI because we are changing the memory mapping, so make sure that only new machine enforce but not older ones.
