   5 * On mips we have two 32bit ABIs - o32 and n32.  The latter
   6 * has bigger registers, so we use it for compat_elf_regset_t.
   7 * The former uses o32_elf_prstatus and PRSTATUS_SIZE/SET_PR_FPVALID
   8 * are used to choose the size and location of ->pr_fpvalid of
   9 * the layout actually used.
