   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. )
