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.
