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