+// Replace by-hand memory_region_init_ram_nomigrate/vmstate_register_ram
+// code sequences with use of the new memory_region_init_ram function.
+// Similarly for the _rom and _rom_device functions.
+// We don't try to replace sequences with a non-NULL owner, because
+// there are none in the tree that can be automatically converted
+// (and only a handful that can be manually converted).
