Hi Yinghai, The new hotplug framework only handles CPU, memory, container and PCI host bridges, so it shouldn't affect acpiphp or pciehp drivers. > > Also I would suggest you to start the new framework stuff after cpu, > memory, pci-root-bus work are all done separately. OK, hope the PCI host bridge hotplug work be merged for 3.8. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
