551bcb75b3 [PATCH] acpiphp: hotplug slot hotplug
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.

e6ad00576f [PATCH] PCI: rpaphp: remove init error condition
The init function for the RPA PCI Hotplug driver returns -ENODEV in the
case that no hotplug-capable slots are detected in the system.  This is
bad, since hot-capable slots can be added after boot to a purely virtual
POWER partition.  This is also bad because DLPAR I/O operations depend
on the rpaphp module.

Change the rpaphp init module to return success for the case of
partitions that own no hotplug-capable slots at boot.  Such slots can be
dynamically added after boot.

0cccd0c206 [PATCH] acpiphp: fix bridge handle
When hotplug slot is under the host bridge,
DEVICE_ACPI_HANDLE(&bus->self->dev) fails since '&bus->self' was not set.
This patch fixes it.

This patch is based on kristen's latest patches.
I tested this patch on my Tiger4.

e27da38141 [PATCH] acpiphp - slot management fix - V4
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)

20416ea540 [PATCH] acpiphp: add dock event handling
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.

15a1ae7487 [PATCH] acpiphp: add new bus to acpi
If we add a new bridge with subordinate busses, we should call make sure
that acpi is notified so that the PRT (if present) can be read and drivers
who have registered on this bus will be notified when it is started.
Also make sure to use the max reserved bus number for the starting the bus
scan.

a246fa4e9f [PATCH] shpchp: Fix slot state handling
Current SHPCHP driver doesn't care about the confliction between
hotplug operation via sysfs and hotplug operation via attention
button. So if those ware conflicted, slot could be an unexpected
state.

This patch changes SHPCHP driver to handle slot state properly. With
this patch, slot events are handled according to the current slot
state as shown at the Table below.

		Table. Slot States and Event Handling
=========================================================================
Slot State		Event and Action
=========================================================================
STATIC			- Go to POWERON state if user initiates
(Slot enabled,		  insertion request via sysfs
 Slot disabled)		- Go to POWEROFF state if user initiates removal
			  request via sysfs
			- Go to BLINKINGON state if user presses
			  attention button when the slot is disabled
			- Go to BLINKINGOFF state if user presses
			  attention button when the slot is enabled

f7391f5325 [PATCH] shpchp: event handling rework
The event handler of SHPCHP driver is unnecessarily very complex. In
addition, current event handler can only a fixed number of events at
the same time, and some of events would be lost if several number of
events happened at the same time.

This patch simplify the event handler by using 'work queue', and it
also fix the above-mentioned issue.

e4e73041ec [PATCH] shpchp - Fix incorrect return value of interrupt handler
Current SHPCHP driver has a bug in its interrupt handler which cause
"IRQ #: nobody cared" oops. This problem can be reproduced easily by
the following operation.

    # cd /sys/bus/pci/slots/<slot#>
    # while true; do echo 1 > attention ; done &

The reason is that when command complete interrupt is raised, current
SHPCHP driver's interrupt handler returns IRQ_NONE regardless of if
the interrupt is handled or not.

This patch fixes this issue.
