* resource.c (print_rlimit64, print_rlimit32, printrusage32, printrusage, sys_times): Use umove_or_printaddr. (decode_rlimit64): Remove. (decode_rlimit): Remove redundant checks. [defined(current_wordsize) && current_wordsize != 4] (decode_rlimit): Define to print_rlimit64. (sys_prlimit64): Replace decode_rlimit64 with print_rlimit64.
