 * FIXME: This came from tools/perf/perf-sys.h, where it was first introduced
 * in c1e028ef40b8d6943b767028ba17d4f2ba020edb, more work needed to make it
 * more closely follow the Linux kernel arch/mips/include/asm/barrier.h file.
 * Probably when we continue work on tools/ Kconfig support to have all the
 * CONFIG_ needed for properly doing that.
