From 38bb171b958480b484e8e980be76c7d3656881ea Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Tue, 11 Jul 2023 17:59:15 +0200 Subject: powerpc/kuap: Fold kuep_is_disabled() into its only user kuep_is_disabled() was introduced by commit 91bb30822a2e ("powerpc/32s: Refactor update of user segment registers") but then all users but one were removed by commit 526d4a4c77ae ("powerpc/32s: Do kuep_lock() and kuep_unlock() in assembly"). Fold kuep_is_disabled() into init_new_context() which is its only user.
