From 8ad33041563a10b34988800c682ada14b2612533 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 27 Mar 2018 23:01:48 +1100 Subject: [PATCH] powerpc/64s: Move cpu_show_meltdown() This landed in setup_64.c for no good reason other than we had nowhere else to put it. Now that we have a security-related file, that is a better place for it so move it.
