* ptyio.c (pty_io_readable): int -> size_t in argument type. * term.h: Update decl. * users.c (trivfs_S_io_write): int -> size_t in AMT argument type. (trivfs_S_io_readable): Likewise. (trivfs_S_io_read): Likewise. Also u_int -> size_t, off_t -> loff_t. (trivfs_S_io_write): Likewise. (trivfs_S_io_map): Add reply port args.
