Without this the kernel may not successfully claim the region as a resource if the bootloader didn't configure the region. With this patch the kernel will always succeed with: pci 0000:00:0a.3: quirk: [io 0x1000-0x103f] claimed by PIIX4 ACPI The lack of the resource claiming is easily reproducible without this patch using current versions of QEMU.
