* Make for_each_efi_memory_desc_in_map() safe on Xen and prevent an
infinte loop - Jan Beulich
* Fix boot error on arm64 Qualcomm platforms by refactoring and
improving the ExitBootServices() hack we already for x86 and moving
it to the libstub - Jeffrey Hugo
* Use correct return data type for of_get_flat_dt_subnode_by_name()
so that we correctly handle errors - Andrzej Hajda
