Subject: [PATCH] ARM: tegra: remove mach/barriers.h
Date: Sun, 10 Jul 2011 14:02:52 -0700	[thread overview]
Message-ID: <1310331772-13310-1-git-send-email-ccross@android.com> (raw)

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.
