From 94cf42f823bc904305b0ee93a09bcd51ba380497 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Thu, 13 Mar 2014 19:00:36 +0100 Subject: arch,hexagon: Convert smp_mb__*() Hexagon uses asm-gemeric/barrier.h and its smp_mb() is barrier(). Therefore we can use the default implementation that uses smp_mb(). Signed-off-by: Peter Zijlstra Acked-by: Paul E.
