Merge branch 'acpi-hotplug'
* 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
