From e69244d29558c947703851a26bfed833945c093a Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Tue, 26 Jun 2018 15:52:38 +0100 Subject: ARM: 8777/1: Hook up SYNC_CORE functionality for sys_membarrier() Exception return implies context synchronization, so we can hook up the SYNC_CORE option to sys_membarrier() simply by selecting the Kconfig option, just like we've done for arm64 already.
