From 920a541397f7b897cb2d0db4be3889df332899f7 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Mon, 26 Feb 2018 13:13:17 +1100 Subject: [PATCH] powerpc/64s: Fix RFI flush dependency on HARDLOCKUP_DETECTOR The backport of commit aa8a5e0062ac ("powerpc/64s: Add support for RFI flush of L1-D cache"), incorrectly placed the new RFI flush code inside an existing #ifdef CONFIG_HARDLOCKUP_DETECTOR block. This has the obvious effect of requiring HARDLOCKUP_DETECTOR to be enabled in order for RFI flush to be enabled, which is a bug. Fix it by moving the #endif up to where it belongs.
