SVN rev 221703 on 2011-05-09 17:34:00Z by jkim
Implement boot-time TSC synchronization test for SMP. This test is executed
when the user has indicated that the system has synchronized TSCs or it has
P-state invariant TSCs. For the former case, we may clear the tunable if it
fails the test to prevent accidental foot-shooting. For the latter case, we
may set it if it passes the test to notify the user that it may be usable.
