From e74c5787940999766ae8cd9731471370b595c3fe Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Thu, 16 Mar 2017 11:20:10 +0000 Subject: [PATCH v2 4.8 02/21] ARM: arm64: activate atomic 64-bit accessors For some reason (probably because there was no user before) the 64-bit atomic access wrappers were commented out so far. As we will need them in the next patch, active (and fix) them now.
