Update.
2001-04-10 Franz Sirl <Franz.Sirl-kernel@lauterbach.com> * elf/elf.h (AT_DCACHEBSIZE, AT_ICACHEBSIZE, AT_UCACHEBSIZE, AT_IGNOREPPC): New defines. * sysdeps/generic/dl-sysdep.c (_dl_show_auxv): Print them. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_STD_AUXV): Define for newer powerpc kernels. * sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Use the standard DL_FIND_ARG_COMPONENTS if __ASSUME_STD_AUXV is defined.
