   4 * FIXME: This came from tools/perf/perf-sys.h, where it was first introduced
   5 * in 620830b6954913647b7c7f68920cf48eddf6ad92, more work needed to make it
   6 * more closely follow the Linux kernel arch/tile/include/asm/barrier.h file.
   7 * Probably when we continue work on tools/ Kconfig support to have all the
   8 * CONFIG_ needed for properly doing that.
