Subject: Re: [PATCH 1/2] elf loader support for auxvec base platform string

Why not just use ELF_HWCAP for this?  It looks like powerpc only has 3 bits
left there (keeping it to 32), but 3 is not 0.  If not that, why not use
dsocaps?  That is, some magic in the vDSO, which glibc already supports on
all machines where it uses the vDSO.  (For how it works, see the use in
arch/x86/vdso/vdso32/note.S for CONFIG_XEN.)


Thanks,
Roland
