Modify the acpiphp driver to use the ACPI dock driver for dock
notifications.  Only load the acpiphp driver if we find we have pci dock
devices.

o hotplug slots add
  When the hot-added PCI device is p2p bridge, acpiphp calls
  find_p2p_bridge() to add hotplug slots.

o hotplug slots remove
  When the hot-removing PCI device is p2p bridge, acpiphp
  calls cleanup_p2p_bridge() to remove hotplug slots.

o notify handler exchange
  When the p2p bridge is added, acpiphp changes the notify
  hanlder.
  If no bridge device is inserted into the hotpluggable PCI
  slot, acpiphp installs the notify handler for function.
  After the p2p bridge hot-add, acpiphp has to install the
  notify handler for bridge. Because, the role of the
  handlers are not same. The hot-remove case is ditto.

shpchprm_acpi.c and pciehprm_acpi.c are nearly identical.  In addition,
there are functions in both these files that are also in acpiphp_glue.c.
This patch will remove duplicate functions from shpchp, pciehp, and
acpiphp and move this functionality to pci_hotplug, as it is not
hardware specific.  Get rid of shpchprm* and pciehprm* files since they
are no longer needed.  shpchprm_nonacpi.c and pciehprm_nonacpi.c are
identical, as well as shpchprm_legacy.c and can be replaced with a
macro.

This patch also changes acpiphp to use the common hpp code.

o This patch removes IDs (for slots management).
o This patch removes the slot register/unregister processes
  from the init/exit phases. Instead, adds these processes
  in the bridge add/cleanup phases.
o Currently, this change doesn't have any meanings. But
  these changes are needed to support p2p bridge(with
  hotplug slot)

These patches add generic dock event handling to acpiphp.  If there are
pci devices that need to be inserted/removed after the dock event, the
event notification will be handed down to the normal pci hotplug event
handler in acpiphp so that new bridges/devices can be enumerated.

Because some dock stations do not have pci bridges or pci devices that
need to be inserted after a dock, acpiphp will remain loaded to handle
dock events even if no hotpluggable pci slots are discovered.

You probably need to have the pci=assign-busses kernel parameter enabled
to use these patches, and you may not allow ibm_acpi to handle docking
notifications and use this patch.

This patch incorporates feedback provided by many.

This patch converts acpiphp to use the generic PCI resource assignment code.
It's quite large, but most of it is deleting the acpiphp_pci and acpiphp_res
files.  It's tested on an hp Integrity rx8620 (which won't work without this
patch).  Testers with other hardware welcomed.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
