OK, thanks.

Hmm... firstly, you mentioned "except architectures, this is only used
under s390" (so I reply we need follow s390), and then you mentioned
"they are useless for arm/arm64" (so I ask whether it can be removed).

Excuse me, as a 'programmer' (at least, I am a 'programmer'), when
programming (assume our discussing belongs to programming), I have to
consider precisely (especially for confirmation words).  ;-)

I will send one patch for removing it from arm and arm64.

Thanks.
