50defa1cca [PATCH] PCI: Add pci_device_shutdown to pci_bus_type
The extra compatability code is not necessary.  Any code still using
the old shutdown method will trigger the warning in driver_register()
instead.

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.

Agreed, looks like an accident.  The patch [1] originally came from Kip
Walker (Broadcom back then) between 2.6.0-test3 and 2.6.0-test4.  As I
recall it was supposed to fix an issue with with PCI aborts being
signalled by the PCI bridge of the Broadcom BCM1250 family of SOCs when
probing behind pci_scan_bridge.  It is undeseriable to disable
PCI_BRIDGE_CTL_MASTER_ABORT in pci_{read,write)_config_* and the
behaviour wasn't considered a bug in need of a workaround, so this was
put in probe.c.

I don't have an affected system at hand, so can't really test but I
propose something like the below patch.

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.

3c0c644188 [PATCH] PCI Hotplug: PCI panic on dlpar add (add pci slot to running partition)
Removing and then adding a PCI slot to a running partition results in
a kernel panic. The current code attempts to add iospace for an entire
root bus, which is inappropriate, and silently fails.  When a pci device
tries to use the iospace, a page fault is taken, as the iospace had not
been mapped, and of course the page fault cannot be resolved.

This only occurs for PCI adapters using pio, which may be why it hadn't
been seen earlier (this seems to have been broken for a while).
This patch has survived testing of dozens of slot add and removes.

9f3f468129 [PATCH] PCI Hotplug: fix up the sysfs file in the compaq pci hotplug driver
The Compaq PCI Hotplug driver was creating 2 sysfs files that contained
nothing but debug information, and had way more than "one value" in
them.  This patch converts the code to use debugfs for these files
instead.

Compile tested only.

121082e2ab [PATCH] PCI: Reduce nr of ptr derefs in drivers/pci/hotplug/pciehp_core.c
Here's a small patch to reduce the nr. of pointer dereferences in
drivers/pci/hotplug/pciehp_core.c

Benefits:
 - micro speed optimization due to fewer pointer derefs
 - generated code is slightly smaller
 - small line length cleanup
 - better readability
