another fid mechanism (as SMB2 that has it divided into two parts:
persistent and violatile).
Also rename variables and refactor the code around the changes.

====================
Please pull this last(?) batch of fixes intended for 3.6...
For the Bluetooth bits, Gustavo says this:
"Here goes probably my last update to 3.6. It includes the two patches
you were ok last week(from Andrzej Kaczmarek), those are critical
ones, and two other fixes one for a system crash and the other for
a missing lockdep annotation."
The referenced fixes from Andrzej prevent attempts to configure devices
that are powered-off.
Along with the Bluetooth fixes, there are a couple of 802.11 fixes.
Emmanuel Grumbach gives us an iwlwifi fix to prevent releasing an
interrupt twice. Luis R. Rodriguez provides a fix for a possible
circular lock dependency in the cfg80211 regulatory enforcement code.
All of these have been in linux-next for a few days. I hope they are
not too late to make the 3.6 release!

Pull a Xen fix from Konrad Rzeszutek Wilk:
"It is a bug-fix when we run the initial PV guest on a AMD K8 machine
and have CONFIG_AMD_NUMA enabled and detect the NUMA topology from the
Northbridge.
We end up in the situation where the initial domain gets too much
information and gets confused and crashes - the fix is to restrict the
domain to get the information - and we do it by just disabling NUMA on
the PV guest (the hypervisor is still able to do its proper NUMA
allocations of guests).
It is OK to disable the PV guest from accessing NUMA data as right now
we do not inject any NUMA node information to the PV guests. When we
do get to that point, then this patch will have to be reverted."

Commit 0d52f54e2e (PCI / ACPI: Make acpiphp
ignore root bridges using PCIe native hotplug) added code that made the
acpiphp driver completely ignore PCIe root complexes for which the kernel
had been granted control of the native PCIe hotplug feature by the BIOS
through _OSC. Later commit 619a5182d1
"PCI hotplug: Always allow acpiphp to handle non-PCIe bridges" relaxed
the constraints to allow acpiphp driver handle non-PCIe bridges under
such a complex. The constraint needs to be relaxed further to allow
acpiphp driver to handle PCIe ports without native PCIe hotplug capability.
Some MR-IOV switch chipsets, such PLX8696, support multiple virtual PCIe
switches and may migrate downstream ports among virtual switches. To
migrate a downstream port from the source virtual switch to the target, the
port needs to be hot-removed from the source and hot-added into the target.
The pciehp driver can't be used here because there are no slots within the
virtual PCIe switch. So acpiphp driver is used to support downstream port
migration. A typical configuration is as below:
[Root without native PCIe HP]
[Upstream port of vswitch without native PCIe HP]
[Downstream port of vswitch with native PCIe HP]
[PCIe endpoint]
Here acpiphp driver will be used to handle root ports and upstream port
in the virtual switch, and pciehp driver will be used to handle downstream
ports in the virtual switch.

This patch changes the implementation of acpi_pci_find_root().
We can access acpi_pci_root without scanning acpi_pci_roots list.
If hostbridge hotplug is supported, acpi_pci_roots list will be
protected by mutex. We should not access acpi_pci_roots list
if preventable to lessen deadlock risk.

This patch changes the function signature of walk_root_bridge().
We can omit _STA, _SEG, and _BBN evaluation by passing not acpi_handle
but acpi_pci_root. Now that acpi_pci_slot_add() which is the only
caller of walk_root_bridge() gets acpi_pci_root structure, changing
signature of walk_root_bridge() is reasonable.

This patch changes .add/.remove interfaces of acpi_pci_driver.
In the current implementation acpi_handle is passed as a parameter
of .add/.remove interface. However, the acpi_pci_root structure
contains more useful information than just the acpi_handle. This
enables us to avoid some useless lookups in each acpi_pci_driver.
Note: This changes interfaces used by acpi_pci_register_driver(), an
exported symbol. This patch updates all the in-kernel users, but any
out-of-kernel acpi_pci_register_driver() users will need updates.

Make sure we keep enough space for terminating NUL character after last
newline. If we have too much data, replace last byte with '.'s to
make overflow visible.
Using hex_dump_to_buffer() is not interesting as it adds more overhead
and does not append the trailing linefeed.

When we bind a device to an ACPI handle, the handle is stored in
dev->archdata.acpi_handle. For such devices, there's no need to
search the acpi_pci_roots list with acpi_get_pci_rootbridge_handle();
we can just use DEVICE_ACPI_HANDLE(dev) directly.
