For ARM, I'd prefer this to be:
unsigned long fd, const struct iovec __user *vec, loff_t pos, unsigned long vlen
to avoid any variance in ABIness which will occur with the argument layout as it currently stands, but that creates a silly argument order. The other option would be for us to define our own version in an ARM ABI independent manner:
ssize_t sys_arm_preadv(unsigned long fd, const struct iovec __user *vec, unsigned long vlen, unsigned long low_pos, unsigned long high_pos)
