Boris Ostrovsky b3cf8528bb xen/balloon: Mark unallocated host memory as UNUSABLE ... Commit f5775e0b61 ("x86/xen: discard RAM regions above the maximum reservation") left host memory not assigned to dom0 as available for memory hotplug. Unfortunately this also meant that those regions could be used by others. Specifically, commit fa564ad963 ("x86/PCI: Enable a 64bit BAR on AMD Family 15h (Models 00-1f, 30-3f, 60-7f)") may try to map those addresses as MMIO. To prevent this mark unallocated host memory as E820_TYPE_UNUSABLE (thus effectively reverting f5775e0b61) and keep track of that region as a hostmem resource that can be used for the hotplug.
