      8  *   a different rlimit ID order in the 5-9 range and want
      9  *   to keep that order for binary compatibility. The reasons
     10  *   are historic and all new rlimits are identical across all
     11  *   arches. If an arch has such special order for some rlimits
     12  *   then it defines them prior including asm-generic/resource.h. )
