From 0da85d1e38b4c186d2248f0239b72d465f5b406c Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 7 May 2015 17:52:19 -0300 Subject: perf tools: Move alpha barrier.h stuff to tools/arch/alpha/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.
