On bootup the E820 "gaps" or E820_RESV regions are marked as
identity regions. Meaning that any lookup done in the P2M
will return the same value: pfn_to_mfn(pfn) == pfn.
This is needed for PCI devices so that drivers can reference
the correct bus address. Unfortunatly there are also PCIe
devices
On bootup the E820 gaps or E820_RESV regions are marked as
