From d3bd708114a37bcb472715818ba21d61ef71e86a Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 8 May 2015 10:02:00 -0300 Subject: perf tools: Move tile barrier.h stuff to tools/arch/tile/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.
