EFI uses 4k page, while xen uses 16k page. For dom0, identity mapping are setup for EFI_ACPI_RECLAIM_MEMORY etc. It is possible when seting up dom0 memory range which may include some EFI_ACPI_RECLAIM_MEMORY due to 4k/16k alignment difference. This patch fix this issue by scaning memory descriptors twice in the first scan, setup dom0 identity mapping in the seconde scan, setup dom0 memory mapping.

Applied. Thanks,
