From 2db56e8606016e33903c64feaed989ffecd66a1b Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Thu, 13 Mar 2014 19:00:36 +0100 Subject: [PATCH] arch,m68k: Convert smp_mb__*() m68k uses asm-generic/barrier.h and its smp_mb() is barrier(), therefore we can use the generic versions that use smp_mb().
