I have the "Procedure Call Standard for the ARM 64-bit Architecture" issue 1.1-beta from [1]. It appears to be different from the 1.0 revision as it lists the types for the ILP32, LP64 and LLP64 models. The previous documentation listed both types with a note that the type shall be unsigned long long on systems with a 32-bit unsigned long. It doesn't say which type should be used when both are 64-bit.
