[PATCH v2 10/12] powerpc/32s: Activate KUAP and KUEP by default

From: Christophe Leroy
Date: Thu Jun 03 2021 - 04:42:15 EST


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.
