From: Yury Norov <yury.no...@gmail.com> ILP32 has 64-bit off_t, to follow modern requirements. But kernel clears top-halves of input registers. It means we have to pass corresponding arguments in a pair, like aarch32 does. In this patch all affected syscalls are redefined. Most of them are taken from arm code.
