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.
