From de4cf3de594f96f5a27f0e2346dd211beb126f88 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Tue, 5 Jul 2016 15:03:43 +1000 Subject: [PATCH] powerpc: Move 64-bit memory reserves to setup_arch() There is really no need to do them that early, early_setup() runs before MMU is on, we should do the strict minimum there to get the MMU going.
