Vincent Whitchurch	39508aab4a	um: Fix order of dtb unflatten/early init ... Scan the tree for reserved memory before unflattening it. As Rob Herring said: | These should be reversed. early_init_fdt_scan_reserved_mem() works on | the flat tree. Reserved memory needs to be reserved before | unflatten_device_tree() starts allocating memory. Though I imagine that | doesn't really matter for UML.
