Catalin Marinas 9623b3732d [ARM] 4241/1: Define mb() as compiler barrier on a uniprocessor system 
Currently, the mb() is defined as a DMB operation on ARMv6, even for
UP systems. This patch defines mb() as a compiler barrier only. For
the SMP case, the smp_* variants should be used anyway and the patch
defines them as DMB.
