If the device being added to Xen is not contained in the ACPI table,
walk the PCI device tree to find a parent that is contained in the ACPI
table before finding the PXM information from this device.
Previously, it would try to get a handle for the device, then the
device's bridge, then the physfn. This changes the order so that it
tries to get a handle for the device, then the physfn, the walks up the
PCI device tree.

physdev_pci_device_add's optarr[] is a zero-sized array and therefore
reference to add.optarr[0] is accessing memory that does not belong to
the 'add' variable.

We can't include <asm/pci_x86.h> if this isn't x86, and we only need
it if CONFIG_PCI_MMCONFIG is enabled.

Since DEVICE_ACPI_HANDLE() is now literally identical to
ACPI_HANDLE(), replace it with the latter everywhere and drop its
definition from include/acpi.h.

The PCI MMCONFIG area is usually reserved via the E820 so the Xen hypervisor
is aware of these regions. But they can also be enumerated in the ACPI
DSDT which means the hypervisor won't know of them until the initial
domain informs it of via PHYSDEVOP_pci_mmcfg_reserved.
This is what this patch does for all of the MCFG regions that the
initial domain is aware of (E820 enumerated and ACPI).

Some SR-IOV devices may use more than one bus number, but there is no real bridges
because that have internal routing mechanism. So need to check whether the bridge is
existing before using it.

Now that the hypercall interface changes are in -unstable, make the
kernel side code not ignore the segment (aka domain) number anymore
(which results in pretty odd behavior on such systems). Rather, if
only the old interfaces are available, don't call them for devices on
non-zero segments at all.

Notifier functions are expected to return NOTIFY_* codes, not -E...
ones. In particular, since the respective hypercalls failing is not
fatal to the operation of the Dom0 kernel, it must be avoided to
return negative values here as those would make it appear as if
NOTIFY_STOP_MASK wa set, suppressing further notification calls to
other interested parties (which is also why we don't want to use
notifier_from_errno() here).
While at it, also notify the user of a failed hypercall.

Register a pci notifier to add (or remove) pci devices to Xen via
hypercalls. Xen needs to know the pci devices present in the system to
handle pci passthrough and even MSI remapping in the initial domain.
