  PCI / ACPI: Use acpi_find_child_device() for child devices lookup
  ACPI / bind: Simplify child device lookups
  ACPI / scan: Use direct recurrence for device hierarchy walks
  ACPI: Introduce acpi_set_device_status()
  ACPI / hotplug: Drop unfinished global notification handling routines
  ACPI / hotplug: Rework generic code to handle suprise removals
  ACPI / hotplug: Move container-specific code out of the core
  ACPI / hotplug: Make ACPI PCI root hotplug use common hotplug code
  ACPI / hotplug: Introduce common hotplug function acpi_device_hotplug()
  ACPI / hotplug: Do not fail bus and device checks for disabled hotplug
