There is no way to interact with a physical PCI slot without
sysfs, so encode the dependency and prevent this build error:
drivers/pci/slot.c: In function 'pci_hp_create_module_link':
drivers/pci/slot.c:327: error: 'module_kset' undeclared
This patch _should_ make pci-sysfs.o depend on CONFIG_SYSFS too,
but we cannot (yet) because the PCI core merrily assumes the
existence of sysfs:
drivers/built-in.o: In function `pci_bus_add_device':
drivers/pci/bus.c:89: undefined reference to `pci_create_sysfs_dev_files'
drivers/built-in.o: In function `pci_stop_dev':
drivers/pci/remove.c:24: undefined reference to `pci_remove_sysfs_dev_files'
So do the minimal bit for now and figure out how to untangle it
later.

Create symbolic link to hotplug driver module in the PCI slot
directory (/sys/bus/pci/slots/<SLOT#>). In the past, we need to load
hotplug drivers one by one to identify the hotplug driver that handles
the slot, and it was very inconvenient especially for trouble shooting.
With this change, we can easily identify the hotplug driver.

The EMI support in pciehp is obviously broken. It is implemented using
struct hotplug_slot_attribute, but sysfs_ops for pci_slot_ktype is NOT
for struct hotplug_slot_attribute, but for struct pci_slot_attribute.
This bug had been there for a long time, maybe it was introduced when
PCI slot framework was introduced. The reason why this bug didn't
cause any problem is maybe the EMI support is not tested at all
because of lack of test environment.
As described above, the EMI support in pciehp seems not to be tested
at all. So this patch removes EMI support from pciehp, instead of
fixing the bug.

Convert uses of pci_find_slot to modern API.
In the conversion sites, we end up calling pci_dev_put() right away.
This may seem like it misses the entire point of doing something like
pci_get_bus_and_slot(), since we drop the reference so soon, but it turns
out we don't actually do much with the returned pci_dev.
I plan on untangling cpqphp further, but clearly cpqphp never worried too
much about a properly refcounted pci_dev anyway. For now, this conversion
seems reasonable, as it gets rid of the last in-tree caller of pci_find_slot.

Instead of making multiple calls to pcibios_get_irq_routing_table, let's
just do it once and save the answer.
The reason we were making multiple calls is because we liked to calculate
its length and perform some loop over it. Instead of open-coding the length
calculation every time, provide it in an inline helper function.
Finally, since pci_print_IRQ_route() is used only for debug, let's only
do it when cpqhp_debug is set.

Apply DeMorgan's theorem:
if ((pdev->revision > 2) || (vendor_id == PCI_VENDOR_ID_INTEL))
turns into
if ((pdev->revision <= 2) && (vendor_id != PCI_VENDOR_ID_INTEL))

An oops can occur if a user attempts to use both PCI logical
hotplug and the ACPI physical hotplug driver (acpiphp) in this
sequence, where $slot/address == $device.
In other words, if acpiphp has claimed a PCI device, and that
device is logically removed, then acpiphp may oops when it
attempts to access it again.
# echo 1 > /sys/bus/pci/devices/$device/remove
# echo 0 > /sys/bus/pci/slots/$slot/power

The root cause of this oops is that the logical remove ("echo 1 >
/sys/bus/pci/devices/$device/remove") destroyed the pci_dev. The
pci_dev struct itself wasn't deallocated because acpiphp kept a
reference, but some of its fields became invalid.
acpiphp doesn't have any real reason to keep a pointer to a
pci_dev around. It can always derive it using pci_get_slot().
If a logical remove destroys the pci_dev, acpiphp won't find it
and is thus prevented from causing mischief.

If a logical hot unplug (remove) is performed on a bridge claimed
by acpiphp and then acpiphp is unloaded, we will encounter an oops.
This is because acpiphp will access the bridge's subordinate bus,
which was released by the user's prior hot unplug.
The solution is to grab a reference on the subordinate PCI bus.
This will prevent the bus from release until acpiphp is unloaded.

A complete re-implementation of fakephp is necessary if it is to
present its former interface (pre-2.6.27, when it broke). The
reason is that PCI hotplug drivers call pci_hp_register(), which
enforces the rule that only one /sys/bus/pci/slots/ file may be
created per physical slot.
The change breaks the old fakephp's assumption that it could
create a file per function. So we re-implement fakephp to avoid
using the standard PCI hotplug API so that we can restore the old
fakephp user interface.
It puts entries in /sys/bus/pci/slots with the names of all PCI
devices/functions, exactly symmetrical to what is shown in
/sys/bus/pci/devices. Each slots/ entry has a "power" attribute,
which works the same way as the fakephp driver's power attribute
has worked.
There are a few improvements over old fakephp, which couldn't handle
PCI devices being added or removed via a means outside of
fakephp's knowledge. If a device was added another way, old fakephp
didn't notice and didn't create the fake slot for it. If a
device was removed another way, old fakephp didn't delete the fake
slot for it (and accessing the stale slot caused an oops).
The new implementation overcomes these limitations. As a
consequence, removing a bridge with other devices behind it now
works as well, which is something else old fakephp couldn't do
previously.
This duplicates a tiny bit of the code in the PCI core that does
this same function. Re-using that code ends up being more
complex than duplicating it, and it makes code in the PCI core
more ugly just to support this legacy fakephp interface
compatibility layer.

Current pciehp disables software notification of adapter presence

of this, there is no way to detect those events on empty slots in the
current pciehp implementation.
According to the past discussion(*), this behavior was introduced to
prevent endless loop that could happen if pcie_isr() runs after power
fault is detected on a certain platform whose stickey power-fault bit
remains on till the slot is powered on again.
(*) http://sourceforge.net/mailarchive/message.php?msg_id=20051130135409.A14918%40unix-os.sc.intel.com

The PCI Express port driver uses 'struct pcie_port_service_id' for
matching port service devices and drivers, but this structure
contains fields that duplicate information from the port device
itself (vendor, device, subvendor, subdevice) and fields that are not
used by any existing port service driver (class, class_mask,
drvier_data). Also, both existing port service drivers (AER and
PCIe HP) don't even use the vendor and device fields for device
matching. Therefore 'struct pcie_port_service_id' can be removed
altogether and the only useful members of it (port_type, service) can
be introduced directly into the port service device and port service
driver structures. That simplifies the code quite a bit and reduces
its size.
