This reverts commit 809d9a8f93bd8504dcc34b16bbfdfd1a8c9bb1ed.
This one isn't quite ready for prime time. It needs more testing and
additional feedback from the ACPI guys.

Using ACPI to find free address space allows us to find a gap for the
unallocated PCI resources or MMIO resources for hotplug devices within
the BIOS allowed PCI regions.
It works by evaluating the _CRS object under PCI0 looking for producer
resources. Then searches the e820 memory space for a gap within these
producer resources.

The recently introduced pci_prepare_to_sleep() needs the following fix,
because there are systems which are not power manageable by ACPI (ie.
ACPI doesn't provide methods to put the device into low power states and
back), but require ACPI hooks to be executed for wake-up to work.

If the offset of PCI device's PM capability in its configuration space,
the mask of states that the device supports PME# from and the D1 and D2
support bits are cached in the corresponding struct pci_dev, the PCI
device PM code can be simplified quite a bit.

Introduce functions pci_prepare_to_sleep() and pci_back_from_sleep(),
to be used by the PCI drivers that want to place their devices into
the lowest power state appropiate for them (PCI_D3hot, if the device
is not supposed to wake up the system, or the deepest state from
which the wake-up is possible, otherwise) while the system is being
prepared to go into a sleeping state and to put them back into D0
during the subsequent transition to the working state.

* Rework PCI device PM initialization so that, if given device is
capable of generating wake-up events, either natively through the
PME# mechanism, or with the help of the platform, its
power.can_wakeup flag is set and its power.should_wakeup flag is
unset as appropriate.
* Make ACPI set the power.can_wakeup flag for devices found to be
wake-up capable by it.
* Make the ACPI wake-up code enable/disable GPEs for devices that
have the wakeup.flags.prepared flag set (which means that their
wake-up power has been enabled).

places and in one of them only it tries to execute _DSW before _PSW,
which is inconsistent with the other two cases.

invoked before the native mechanism, if necessary. Also, make
the function check if the device is power manageable by the
platform before invoking the platform callback.
This may matter if the device dependent on additional power
resources controlled by the platform is being put into D0, in which
case those power resources must be turned on before we attempt to
handle the device itself.

[PCI] pci-9: Kill per-architecture pcibios_update_resource()
Kill pcibios_update_resource(), replacing it with pci_update_resource().
pci_update_resource() uses pcibios_resource_to_bus() to convert a
resource to a device BAR - the transformation should be exactly the
same as the transformation used for the PCI bridges.
pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to
set the high 32-bits to anything non-zero - currently no architecture
attempts to do something different. If anyone cares, please fix; I'm
going to reflect current behaviour for the time being.
Ivan pointed out the following architectures need to examine their
pcibios_update_resource() implementation - they should make sure that
this new implementation does the right thing. #warning's have been
added where appropriate.
ia64
mips
mips64
This cset also includes a fix for the problem reported by AKPM where
64-bit arch compilers complain about the resource mask being placed
in a u32.

Current pciehp driver saves its private data pointer into pci_dev
structure using pci_set_drvdata()/pci_get_drvdata(). But because
pciehp is not a pci device driver but a PCI Express service driver, it
should save its private data pointer into pcie_device structure using
set_service_data()/get_service_data().

Currently, pciehp driver enables command completed interrupt as follows.
(1) Don't enable at initialization.
(2) Enable command completed interrupt whenever pciehp issues a
command, if the command doesn't attempt to disable the interrupt.
(3) Disable command completed interrupt at driver unloading.
Once we enable command completed interrupt, we don't need to re-enable
it for every command. So we can simplify above steps as follows:
(1) Enable command completed interrupt at initialization.
(2) No special sequence for command completed interrupt.
(3) Disable command completed interrupt at driver unloading.

Current pciehp driver's intialization sequence is as follows:
(1) initialize controller data structure
(2) install interrupt handler
(3) enable software notification
(4) initialize controller specific slot data structure
(5) initialize generic slot data structure and register it to pci hotplug core
The interrupt handler of pciehp assumes that controller specific slot
data structure is already initialized. However, it is installed at (2)
before initializing controller specific slot data structure at
(4). Because of this, pciehp driver cannot handle the following cases
properly.
- If devices that shares IRQ with pciehp raise interrupts between (2) and (4).
- If hotplug events (e.g. MRL open) happen between (3) and (4).
We already have a workaround for this problem ("pciehp: fix NULL
dereference in interrupt handler: dbd79aed1aea2bece0bf43cc2ff3b2f9baf48a08).
But we still need fundamental fix.
This patch fix the problem by changing the initilization sequence as follows:
(1) initialize controller data structure
(2) initialize controller specific slot data structure
(3) install interrupt handler
(4) enable software notification
(5) initialize generic slot data structure and register it to pci hotplug core

Convert printks to use dev_printk().
I converted pr_debug() to dev_dbg(). Both use KERN_DEBUG and are enabled
only when DEBUG is defined.
I converted printk(KERN_DEBUG) to dev_printk(KERN_DEBUG), not to dev_dbg(),
because dev_dbg() is only enabled when DEBUG is defined.
I converted DBG(KERN_INFO) (only in setup-bus.c) to dev_info(). The DBG()
name makes it sound like debug, but it's been enabled forever, so dev_info()
preserves the previous behavior.
I tried to make the resource assignment formats more consistent, e.g.,
"BAR %d: got res [%#llx-%#llx] bus [%#llx-%#llx] flags %#lx\n"
instead of sometimes using "start-end" and sometimes using "size@start".
I'm not attached to one or the other; I'd just like them consistent.

On x86, we do early PCI probing to apply some quirks for chipset bugs.
However, in a recent cleanup (7bcbc78dea92fdf0947fa48e248da3c993a5690f) a
thinko was introduced that causes us to probe all subfunctions of even single
function devices (a function was factored out of an inner loop and a "break"
became a "return"). Fix that up by making check_dev_quirk() return a value so
we can keep the factored code intact.

ACPI PM: Add possibility to change suspend sequence
There are some systems out there that don't work correctly with
our current suspend/hibernation code ordering. Provide a workaround
for these systems allowing them to pass 'acpi_sleep=old_ordering' in
the kernel command line so that it will use the pre-ACPI 2.0 ("old")
suspend code ordering.
Unfortunately, this requires us to add a platform hook to the
resuming of devices for recovering the platform in case one of the
device drivers' .suspend() routines returns error code. Namely,
ACPI 1.0 specifies that _PTS should be called before suspending
devices, but _WAK still should be called before resuming them in
order to undo the changes made by _PTS. However, if there is an
error during suspending devices, they are automatically resumed
without returning control to the PM core, so the _WAK has to be
called from within device_resume() in that cases.
The patch also reorders and refactors the ACPI suspend/hibernation
code to avoid duplication as far as reasonably possible.

Get rid of a superfluous acpi_pm_device_sleep_state() parameter. The
only legitimate value of that parameter must be derived from the first
parameter, which is what all the callers already do. (However, this
does not address the fact that ACPI still doesn't set up those flags.)

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.

Currently, /sys/bus/pci/slots/ only exposes hotplug attributes when a
hotplug driver is loaded, but PCI slots have attributes such as address,
speed, width, etc. that are not related to hotplug at all.
Introduce pci_slot as the primary data structure and kobject model.
Hotplug attributes described in hotplug_slot become a secondary
structure associated with the pci_slot.
This patch only creates the infrastructure that allows the separation of
PCI slot attributes and hotplug attributes. In this patch, the PCI
hotplug core remains the only user of this infrastructure, and thus,
/sys/bus/pci/slots/ will still only become populated when a hotplug
driver is loaded.
A later patch in this series will add a second user of this new
infrastructure and demonstrate splitting the task of exposing pci_slot
attributes from hotplug_slot attributes.
- Make pci_slot the primary sysfs entity. hotplug_slot becomes a
subsidiary structure.
o pci_create_slot() creates and registers a slot with the PCI core
o pci_slot_add_hotplug() gives it hotplug capability
- Change the prototype of pci_hp_register() to take the bus and
slot number (on parent bus) as parameters.
- Remove all the ->get_address methods since this functionality is
now handled by pci_slot directly.

This patch unhides the SMBus on Compaq Deskpro EN
SFF P667 with the Intel 815E chipset. Unhiding it reveals
a THMC51 hardware monitoring chip.
Jean Delvare has checked that this machine has no ACPI
magic touching the SMBus nor the hardware monitoring chip,
so this should be safe.
The patch was tested on Fedora Core 9 with 2.6.25.4 kernel.

While refreshing my physical PCI slot series against upstream, I
noticed a few simple sparse/compile warnings that were easy to
fix.
Fix the following sparse warnings in PCIe:
drivers/pci/pcie/aer/aerdrv.c:86:6: warning: symbol 'pci_no_aer'
was not declared. Should it be static?
drivers/pci/pcie/portdrv_bus.c:21:17: warning: symbol
'pcie_port_bus_type' was not declared. Should it be static?

The destination of goto error also does a kfree(g_iommus), so it is not
correct to do one here.
