The existing interface only has a pre-order callback. This change
adds an additional parameter for a post-order callback which will
be more useful for bus scans. ACPICA BZ 779.Also update the external calls to acpi_walk_namespace.

Similar to commit b6adc195 (PCI hotplug: acpiphp wants a 64-bit
_SUN), pci_slot.ko reads and creates sysfs directories based on
the _SUN method.Certain HP platforms return 64 bits in _SUN. This change to
pci_slot.ko allows us to see the correct sysfs directories.Reported-by: Chad Smith

If a logical hot unplug (remove) is performed on a physical PCI slot's
parent bridge, and then pci_slot is unloaded, we will encounter an oops:[] kobject_release+0x9a/0x290

Slot detection drivers can co-exist with hotplug drivers. The names
of the detected/claimed slots may be different depending on module
load order.For legacy reasons, we need to allow hotplug drivers to override
the slot name if a detection driver is loaded first (and they find
the same slots).Creating and overriding slot names should be an atomic operation,
otherwise you get a locking nightmare as various drivers race to
call pci_create_slot().pci_create_slot() is already serialized by grabbing the pci_bus_sem.
We update the API and add a 'hotplug' param, which is:
set if the caller is a hotplug driver
NULL if the caller is a detection driverpci_create_slot() does not actually use the 'hotplug' parameter in this
patch. A later patch will add the logic that uses it.Cc: kristen.c.accardi@intel.com

As of version 2.0, ACPI can return 64-bit integers. The current
acpi_evaluate_integer only supports 64-bit integers on 64-bit platforms.
Change the argument to take a pointer to an acpi_integer so we support
64-bit integers on all platforms.lenb: replaced use of "acpi_integer" with "unsigned long long"

I get warnings about 'device' possibly being used uninitialised. While
I can deduce this is not true, it seems that GCC can't. This patch
changes `check_slot' to return device on success and -1 on error, which
shuts GCC up.Acked-by: Alex Chiang

Juha Leppnen noticed that an error path in register_slot() wasn't
returning appropriately, leading to a condition where we might access a
kfree'ed pointer, so let's fix that.Additionally, fix up the copyright information in the file while
we're in there.Signed-off-by: Alex Chiang

Detect all physical PCI slots as described by ACPI, and create entries in
/sys/bus/pci/slots/.Not all physical slots are hotpluggable, and the acpiphp module does not
detect them. Now we know the physical PCI geography of our system, without
caring about hotplug.[kaneshige.kenji@jp.fujitsu.com: export-kobject_rename-for-pci_hotplug_core]
