From 1bb2bae2e6c7d94e3bc1fdce06baf31b8d811ed6 Mon Sep 17 00:00:00 2001 From: Russell Currey Date: Thu, 18 Apr 2019 16:51:22 +1000 Subject: powerpc/mm/radix: Use KUEP API for Radix MMU Execution protection already exists on radix, this just refactors the radix init to provide the KUEP setup function instead. Thus, the only functional change is that it can now be disabled.
