The situation for Arm is fundamentally different from that for ARC. For ARC, you only need a single public stat structure (using 64-bit times and offsets). For Arm, a third public stat structure will need to be added alongside the existing two, initially used internally in 64-bit-time stat functions that aren't exported from glibc, eventually to be used with _TIME_BITS=64 with the 64-bit-time stat interfaces exported once all the _TIME_BITS=64 interfaces are ready. -- Joseph S.
