327 *
328 * DESCRIPTION: Called from acpi_walk_namespace. Expects each object to be a
329 * control method under the _GPE portion of the namespace.
330 * Extract the name and GPE type from the object, saving this
331 * information for quick lookup during GPE dispatch. Allows a
332 * per-owner_id evaluation if execute_by_owner_id is TRUE in the
333 * walk_info parameter block.
334 *
335 * The name of each GPE control method is of the form:
336 * "_Lxx" or "_Exx", where:
337 * L - means that the GPE is level triggered
338 * E - means that the GPE is edge triggered
339 * xx - is the GPE number [in HEX]
340 *
341 * If walk_info->execute_by_owner_id is TRUE, we only execute examine GPE methods
342 * with that owner.
343 * If walk_info->enable_this_gpe is TRUE, the GPE that is referred to by a GPE
344 * method is immediately enabled (Used for Load/load_table operators)
