I think it would be best to clear bit 35 of msr c001_102a in the AP cores as well as the BSP core. Otherwise, the OS might see AP cores having slightly lower performance than the BSP core. This bit affects family 10h revC and newer (45 nm).
Ok, so here's a patch adding this. Clearing bit 35 is done unconditionally for all fam10 cpus, is that ok? Setting is done based on processor type in defaults.h, as before.
