ACPI: Add support for acpi_load_table/acpi_unload_table_id
Make acpi_load_table() available for use by removing it from the #ifdef ACPI_FUTURE_USAGE. Also add a new routine used to unload an ACPI table of a given type and "id" - acpi_unload_table_id(). The implementation of this new routine was almost a direct copy of existing routine acpi_unload_table() - only difference being that it only removes a specific table id instead of ALL tables of a given type. The SN hotplug driver (sgi_hotplug.c) now uses both of these interfaces to dynamically load and unload SSDT ACPI tables. Also, a few other ACPI routines now used by the SN hotplug driver are exported (since the driver can be a loadable module): acpi_ns_map_handle_to_node acpi_ns_convert_entry_to_handle acpi_ns_get_next_node Signed-off-by: Aaron Young <ayoung@sgi.com> Cc: Greg KH <greg@kroah.com> Cc: "Luck, Tony" <tony.luck@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Len Brown <len.brown@intel.com>
