Landed in mainline as 9f5bd8f1471d on 2021-06-16.
Now that KUAP and KUEP have been significantly optimised and can be disabled at boot time using 'nosmap' and 'nosmep' kernel parameters, them can be active by default like in other powerpc platforms. It is still possible to disable them completely in the configuration.
