On an slightly unrelated note; do we want to clear bit 35 here as well?
At the moment, this is only done for the BSP, causing the MSR settings
to be inconsistent after boot.  I see that errata 343 indicates that
this should be cleared after CAR is disabled, so it might not matter all
that much for the APs...
