For context, this change will also allow for more consistent update of the Glibc manual which in turn will help with introducing memory protection keys on AArch64 targets. Applies to 5bc55a333a2f (tag: v6.13-rc7). Note that I couldn't build ppc tests so I would appreciate if someone could check the 3rd patch. Thank you!
