Hello,

This patch set enables the use of PCI Express link up and link down events
for Hotplug or Unplug. The requirement of such a feature was originally
discussed here:

http://www.spinics.net/lists/linux-pci/msg05783.html
http://www.spinics.net/lists/hotplug/msg05801.html

Patch [1/4]: makes a function non-static for use by patch 2.
Patch [2/4]: Contains the bulk logic to allow link events to be used
             for hotplug and removal.
Patch [3/4]: Makes the pciehp_power_thread() lock free by making it
             look at a work info->req instead of slot->state.
Patch [4/4]: Introduce slot->hotplug_lock to serialize the hotplug
             operations.

I'd appreciate if you could please review and provide me with any comments.

Thanks,

Rajat
