From e2164f0406db75cb1ae0bf49ae7915f0ab10e201 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 8 May 2015 09:40:36 -0300 Subject: perf tools: Move mips barrier.h stuff to tools/arch/mips/include/asm/barrier.h We will need it for atomic.h, so move it from the ad-hoc tools/perf/ place to a tools/ subset of the kernel arch/ hierarchy.
