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.
