2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: Alex Chiang commit a32615a1a661f83661e8a26c3bc7763f716da8f3 upstream. We no longer need to manage our version of hotplug_slot->name since the PCI and hotplug core manage it on our behalf. Now, we simply advise the PCI core of the name that we would like, and let the core take care of the rest. Additionally, slightly rearrange the members of struct slot so they are naturally aligned to eliminate holes.
