How about this:

          /* Here the reloc_rw_mask is not testing whether the section should
             be read-only or not, but whether the dynamic link will have to
             do something.  If so, we wish to segregate the data in order to
             minimize cache misses inside the dynamic linker.  If the data
             has a section attribute, ignore reloc_rw_mask() so that all data
             in a given named section is catagorized in the same way.  */
