From 2b0aaaf11a000adb1d1de29953318e6ede6c302b Mon Sep 17 00:00:00 2001 From: Colin Cross Date: Sun, 10 Jul 2011 13:54:02 -0700 Subject: [PATCH] ARM: tegra: remove mach/barriers.h The barriers implemented in arch/arm/mach-tegra/mach/barriers.h are exactly the same as the default barriers implemented in arch/arm/include/asm/system.h. Remove barriers.h from Tegra, and don't select ARCH_HAS_BARRIERS.
