From c4bd6cb87c9e28a7d9f4a97db5a06cc538eb5e48 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Tue, 5 Jul 2016 15:03:42 +1000 Subject: powerpc: Move 64-bit feature fixup earlier Make it part of early_setup() as we really want the feature fixups to be applied before we turn on the MMU since they can have an impact on the various assembly path related to MMU management and interrupts. This makes 64-bit match what 32-bit does.
