jhb 55d0376a65 On some Intel CPUs with a P-state but not C-state invariant TSC the TSC ... may also halt in C2 and not just C3 (it seems that in some cases the BIOS advertises its C3 state as a C2 state in _CST). Just play it safe and disable both C2 and C3 states if a user forces the use of the TSC as the timecounter on such CPUs.
