I'm working to make the Linux/ACPI code handle hotplug notification events. This should ultimately allow us to remove the existing hotplug code scattered through the ACPI device drivers. This is a long series of cleanups that should cause no functional change, but will make it easier to call acpi_bus_scan() from the notification path. Comments and testing reports welcome. Boot logs with CONFIG_ACPI_DEBUG=y and "acpi.debug_layer=0x00010000" will be helpful in debugging any issues.
