 * 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
