Much of turbostat can now run with perf, rather than using the MSR driver Some of turbostat can now run as a regular non-root user. Add some new output columns for some new GFX hardware. [This patch updates the version, but otherwise changes no function; it touches up some checkpatch issues from previous patches] Signed-off-by: Len Brown <len.brown@intel.com>
