That makes perfect sense, thanks for explaining that. So on pre-ISA3.0

Ahem. I already said that this has nothing to do with ISA 3.0. The feature is available on the Fedora builders, for example, which are not ISA 3.0.

Are we interested in adding this support right know given the bugs
and potential future changes?

Yes, I think even with the current set of kernel bugs, the whole thing is still good enough for protecting the GOT and flip access rights in _dl_fixup.

Thanks,
Florian
