* acpi-hotplug:
  ACPI / scan: ACPI device object sysfs attribute for _STA evaluation
  ACPI / hotplug / driver core: Handle containers in a special way
  ACPI / hotplug: Add demand_offline hotplug profile flag
  ACPI / bind: Move acpi_get_child() to drivers/ide/ide-acpi.c
  ACPI / bind: Pass struct acpi_device pointer to acpi_bind_one()
  ACPI / bind: Rework struct acpi_bus_type
  ACPI / bind: Redefine acpi_preset_companion()
  ACPI / bind: Redefine acpi_get_child()
  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
  ACPI / scan: Add acpi_device objects for all device nodes in the namespace
  ACPI / scan: Define non-empty device removal handler
