Only on Intel. Others restrict prefetches on permissions.

I think this might even be fixed by microcode patches on Intel, at least os specific, looking at the first address bit.

If they could have done microcode patches they would have done, suggesting they can't.

Suse already has them.

I guess Intel only focused on Windows NT for several months, and there it's not so easy as on Linux.
