commit 31cbd18a8b9b04ff9b1997c1f41effa57af4a700 Author: Andre Przywara <andre.przywara@xxxxxxx> AuthorDate: Thu Mar 16 11:20:10 2017 +0000 Commit: Julien Grall <julien.grall@xxxxxxx> CommitDate: Fri Jun 14 15:45:59 2019 +0100 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.
