Merge branch 'acpi-ost'
* acpi-ost: ACPI: Drop acpi_evaluate_hotplug_ost() and ACPI_HOTPLUG_OST ACPI: use device name LNXSYBUS.xx for ACPI \_SB and \_TZ objects ACPI / processor: use acpi_evaluate_ost() to replace open-coded version ACPI / PAD / xen: use acpi_evaluate_ost() to replace open-coded version ACPI / PAD: use acpi_evaluate_ost() to replace open-coded version ACPI: rename acpi_evaluate_hotplug_ost() to acpi_evaluate_ost()
