[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. Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
